Leviticus 14:5

Killing the bird and sprinkling its blood (Leviticus 14:7) is similar to Exodus 24:6–8. This is where Moses sprinkled all of Israel with blood to establish them as God's covenant community. In these verses, they cleansed the individual by sprinkling them with blood and allowed them to return to the community. They also used fresh water in cleansing ceremonies and in preparing sacrifices (Numbers 8:7; Leviticus 1:9, 13).

To fully understand these verses about purifying infected people, read them with Leviticus 13:1–46.

the priest shall command that one of the birds be killed . . . over running water--As the blood of a single bird would not have been sufficient to immerse the body of another bird, it was mingled with spring water to increase the quantity necessary for the appointed sprinklings, which were to be repeated seven times, denoting a complete purification. (See Kg2 5:10; Psa 51:2; Mat 8:4; Luk 5:14). The living bird being then set free, in token of the leper's release from quarantine, the priest pronounced him clean; and this official declaration was made with all solemnity, in order that the mind of the leper might be duly impressed with a sense of the divine goodness, and that others might be satisfied they might safely hold intercourse with him. Several other purifications had to be gone through during a series of seven days, and the whole process had to be repeated on the seventh, ere he was allowed to re-enter the camp. The circumstance of a priest being employed seems to imply that instruction suitable to the newly recovered leper would be given, and that the symbolical ceremonies used in the process of cleansing leprosy would be explained. How far they were then understood we cannot tell. But we can trace some instructive analogies between the leprosy and the disease of sin, and between the rites observed in the process of cleansing leprosy and the provisions of the Gospel. The chief of these analogies is that as it was only when a leper exhibited a certain change of state that orders were given by the priest for a sacrifice, so a sinner must be in the exercise of faith and penitence ere the benefits of the gospel remedy can be enjoyed by him. The slain bird and the bird let loose are supposed to typify, the one the death, and the other the resurrection of Christ; while the sprinklings on him that had been leprous typified the requirements which led a believer to cleanse himself from all filthiness of the flesh and spirit, and to perfect his holiness in the fear of the Lord.

Here, I. It is supposed that the plague of the leprosy was not an incurable disease. Uzziah's indeed continued to the day of his death, and Gehazi's was entailed upon his seed; but Miriam's lasted only seven days: we may suppose that it often wore off in process of time. Though God contend long, he will not contend for ever.
II. The judgment of the cure, as well as that of the disease, was referred to the priest. He must go out of the camp to the leper, to see whether his leprosy was healed, Lev 14:3. And we may suppose the priest did not contract any ceremonial uncleanness by coming near the leper, as another person would. It was in mercy to the poor lepers that the priests particularly had orders to attend them, for the priests' lips should keep knowledge; and those in affliction have need to be instructed both how to bear their afflictions and how to reap benefit by them, have need of the word, in concurrence with the rod, to bring them to repentance; therefore it is well for those that are sick if they have these messengers of the Lord of hosts with them, these interpreters, to show unto them God's uprightness, Job 33:23. When the leper was shut out, and could not go to the priests, it was well that the priests might come to him. Is any sick? Let him send for the elders, the ministers, Jam 5:14. If we apply it to the spiritual leprosy of sin, it intimates that when we withdraw from those who walk disorderly, that they may be ashamed, we must not count them as enemies, but admonish them as brethren, Th2 3:15. And also that when God by his grace has brought those to repentance who were shut out of communion for scandal, they ought with tenderness, and joy, and sincere affection, to be received in again. Thus Paul orders concerning the excommunicated Corinthian that when he had given evidences of his repentance they should forgive him, and comfort him, and confirm their love towards him, Co2 2:7, Co2 2:8. And ministers are entrusted by our Master with the declarative power of loosing as well as binding: both must be done with great caution and deliberation, impartially and without respect of persons, with earnest prayer to God for directions, and a sincere regard to the edification of the body of Christ, due care being always taken that sinners may not be encouraged by an excess of lenity, nor penitents discouraged by an excess of severity. Wisdom and sincerity are profitable to direct in this case.
III. If it was found that the leprosy was healed, the priest must declare it with a particular solemnity. The leper or his friends were to get ready two birds caught for this purpose (any sort of wild birds that were clean), and cedar-wood, and scarlet, and hyssop; for all these were to be used in the ceremony. 1. A preparation was to be made of blood and water, with which the leper must be sprinkled. One of the birds (and the Jews say, if there was any difference, it must be the larger and better of the two) was to be killed over an earthen cup of spring water, so that the blood of the bird might discolour the water. This (as some other types) had its accomplishment in the death of Christ, when out of his pierced side there came water and blood, Joh 19:34. Thus Christ comes into the soul for its cure and cleansing, not by water only, but by water and blood, Jo1 5:6. 2. The living bird, with a little scarlet wool, and a bunch of hyssop, must be fastened to a cedar stick, dipped in the water and blood, which must be so sprinkled upon him that was to be cleansed, Lev 14:6, Lev 14:7. The cedar-wood signified the restoring of the leper to his strength and soundness, for that is a sort of wood not apt to putrefy. The scarlet wool signified his recovering a florid colour again, for the leprosy made him white as snow. And the hyssop intimated the removing of the disagreeable scent which commonly attended the leprosy. The cedar the stateliest plant, and hyssop the meanest, are here used together in this service (see Kg1 4:33); for those of the lowest rank in the church may be of use in their place, as well as those that are most eminent, Co1 12:2. Some make the slain bird to typify Christ dying for our sins, and the living bird Christ rising again for our justification. The dipping of the living bird in the blood of the slain bird intimated that the merit of Christ's death was that which made his resurrection effectual for our justification. He took his blood with him into the holy place, and there appeared a lamb as it had been slain. The cedar, scarlet wool, and hyssop, must all be dipped in the blood; for the word and ordinances, and all the operations of the Spirit, receive their efficacy for our cleansing from the blood of Christ. The leper must be sprinkled seven times, to signify a complete purification, in allusion to which David prays, Wash me thoroughly, Psa 51:2. Naaman was directed to wash seven times, Kg2 5:10. 3. The living bird was then to be let loose in the open field, to signify that the leper, being cleansed, was now no longer under restraint and confinement, but might take his liberty to go where he pleased. But this being signified by the flight of a bird towards heaven was an intimation to him henceforward to seek the things that are above, and not to spend this new life to which God had restored him merely in the pursuit of earthly things. This typified that glorious liberty of the children of God to which those are advanced who through grace are sprinkled from an evil conscience. Those whose souls before bowed down to the dust (Psa 44:25), in grief and fear, now fly in the open firmament of heaven, and soar upwards upon the wings of faith and hope, and holy love and joy. 4. The priest must, upon this, pronounce him clean. It was requisite that this should be done with solemnity, that the leper might himself be the more affected with the mercy of God to him in his recovery, and that others might be satisfied to converse with him. Christ is our priest, to whom the Father has committed all judgment, and particularly the judgment of the leprosy. By his definitive sentence impenitent sinners will have their everlasting portion assigned them with the unclean (Job 36:14), out of the holy city; and all that by his grace are cured and cleansed shall be received into the camp of the saints, into which no unclean thing shall enter. Those are clean indeed whom Christ pronounces so, and they need not regard what men say of them. But, though Christ was the end of this law for righteousness, yet being in the days of his flesh made under the law, which as yet stood unrepealed, he ordered those lepers whom he had cured miraculously to go and show themselves to the priest, and offer for their cleansing according to the law, Mat 8:4; Luk 17:14. The type must be kept up till it was answered by its antitype. 5. When the leper was pronounced clean, he must wash his body and his clothes, and shave off all his hair (Lev 14:8), must still tarry seven days out of the camp, and on the seventh day must do it again, Lev 14:9. The priest having pronounced him clean from the disease, he must make himself as clean as ever he could from all the remains of it, and from all other defilements, and he must take time to do this. Thus those who have the comfort of the remission of their sins, by the sprinkling of the blood of Christ upon their consciences, must with the utmost care and caution cleanse themselves from all filthiness both of flesh and spirit, and thoroughly purge themselves from their old sins; for every one that hath this hope in him will be concerned to purify himself.

And the priest shall go forth. This is the examination, which was more fully treated of in the last chapter, without which it was not lawful to receive him who had been once rejected. The priest's command, which is mentioned immediately afterwards, I refer to the Levites, some one of whom probably accompanied the priest to prepare the sacrifice, that thus the priests might only discharge the principal duty. The sum of the rite respecting the two birds tends to this, that the cleansing from leprosy was a kind of resurrection Two birds were placed before their eyes; the liberty of one was purchased by the blood of the other; because the former was not let go until it had been first dipped in the blood and the water; and thus the matter of sprinkling was prepared for the man's purification. The sevenfold repetition was intended to impress more deeply on men's memories a continual meditation on God's grace; for we know that by this number perfection is often expressed in Scripture. With the same object, he who had been cured shaved his hair, and washed in water. Yet he did not return home on the first day, but on the eighth. Meantime, on the seventh day he shaved his beard, and his eyebrows, and all the hair of his head; he washed himself and his garments, and then proceeded to the sacrifice. So difficult is it to accustom men to a serious acknowledgment of the two points, to hold their vice in detestation, and worthily to estimate the grace of God whereby they are delivered.

Over running water - Literally, living, that is, spring water. The meaning appears to be this: Some water (about a quarter of a log, an eggshell and a half full, according to the rabbins) was taken from a spring, and put into a clean earthen vessel, and they killed the bird over this water, that the blood might drop into it; and in this blood and water mixed, they dipped the instrument before described, and sprinkled it seven times upon the person who was to be cleansed. The living or spring water was chosen because it was purer than what was taken from pits or wells, the latter being often in a putrid or corrupt state; for in a ceremony of purifying or cleansing, every thing must be as pure and perfect as possible.

And the priest shall command that one of the birds be killed,.... That is, shall command another priest to kill one of them, or an Israelite, as Aben Ezra; and who also observes, that some say the leper, or the butcher, as the Targum of Jonathan; the killing of this bird, not being a sacrifice, might be done without the camp, as it was, and not at the altar, near to which sacrifices were slain, and where they were offered: and this was to be done

in an earthen vessel over running water: this vessel, according to the Jewish traditions (a), was to be a new one, and a fourth part of a log of running water was to be put into it, and then the bird was to be killed over it, and its blood squeezed into it, and then a hole was dug, and it was buried before the leprous person; and so it should be rendered, "over an earthen vessel", as it is in the Tigurine version, and by Noldius (b); for how could it be killed in it, especially when water was in it? the killing of this bird may have respect to the sufferings, death, and bloodshed of Christ, which were necessary for the purging and cleansing of leprous sinners, and which were endured in his human nature, comparable to an earthen vessel, as an human body sometimes is; see 2 Corinthians 4:7; for he was crucified through weakness, and was put to death in the flesh, 2 Corinthians 13:4; and the running or living water mixed with blood may denote both the sanctification and justification of Christ's people by the water and blood which sprung from his pierced side, and the continual virtue thereof to take away sin, and free from it; or the active and passive obedience of Christ, which both together are the matter of a sinner's justification before God.

(a) Negaim, c. 14. sect. 1.((b) Ebr. Concord. part. p. 64. No. 318.

To wit, by some other man. The priest did not kill it himself, because it was not properly a sacrifice, as being killed without the camp, and not in that place to which all sacrifices were confined; and if it had been a sacrifice, that might be killed by another, so long as the sprinkling of the blood of it, which was the most proper and essential act in the sacrifice, was done by the priest.

Over running water; it seems to be a metathesis or transplacing of words, for over running water put

in an earthen vessel. Thus the blood of the bird and the water were mixed together, partly for the conveniency of sprinkling, and partly to signify Christ, who came by water and blood, . The running water, i.e. spring or river water, by its liveliness and motion did fitly. signify the restoring of liveliness to the leper, who was in a manner dead with his leprosy, as was noted before.

Purification of the leper, after his recovery from his disease. As leprosy, regarded as a decomposition of the vital juices, and as putrefaction in a living body, was an image of death, and like this introduced the same dissolution and destruction of life into the corporeal sphere which sin introduced into the spiritual; and as the leper for this very reason as not only excluded from the fellowship of the sanctuary, but cut off from intercourse with the covenant nation which was called to sanctification: the man, when recovered from leprosy, was first of all to be received into the fellowship of the covenant nation by a significant rite of purification, and then again to be still further inducted into living fellowship with Jehovah in His sanctuary. Hence the purification prescribed was divided into two acts, separated from one another by an interval of seven days.
Lev 14:2-8
The first act (Lev 14:2-8) set forth the restoration of the man, who had been regarded as dead, into the fellowship of the living members of the covenant nation, and was therefore performed by the priest outside the camp.
Lev 14:2-4
On the day of his purification the priest was to examine the leper outside the camp; and if he found the leprosy cured and gone (מן נרפּא, const. praegnans, healed away from, i.e., healed and gone away from), he was to send for (lit., order them to fetch or bring) two living (חיּות, with all the fulness of their vital power) birds (without any precise direction as to the kind, not merely sparrows), and (a piece of) cedar-wood and coccus (probably scarlet wool, or a little piece of scarlet cloth), and hyssop (see at Exo 12:22).
Lev 14:5-7
The priest was to have one of the birds killed into an earthen vessel upon fresh water (water drawn from a fountain or brook, Lev 15:13; Gen 26:19), that is to say, slain in such a manner that its blood should flow into the fresh water which was in a vessel, and should mix with it. He was then to take the (other) live bird, together with the cedar-wood, scarlet, and hyssop, and dip them (these accompaniments) along with the bird into the blood of the one which had been killed over the water. With this the person cured of leprosy was to be sprinkled seven times (see Lev 4:6) and purified; after which the living bird was to be "let loose upon the face of the field," i.e., to be allowed to fly away into the open country. The two birds were symbols of the person to be cleansed. The one let loose into the open country is regarded by all the commentators as a symbolical representation of the fact, that the former leper was now imbued with new vital energy, and released from the fetters of his disease, and could now return in liberty again into the fellowship of his countrymen. But if this is established, the other must also be a symbol of the leper; and just as in the second the essential point in the symbol was its escape to the open country, in the first the main point must have been its death. Not, however, in this sense, that it was a figurative representation of the previous condition of the leper; but that, although it was no true sacrifice, since there was no sprinkling of blood in connection with it, its bloody death was intended to show that the leper would necessarily have suffered death on account of his uncleanness, which reached to the very foundation of his life, if the mercy of God had not delivered him from this punishment of sin, and restored to him the full power and vigour of life again. The restitution of this full and vigorous life was secured to him symbolically, by his being sprinkled with the blood of the bird which was killed in is stead. But because his liability to death had assumed a bodily form in the uncleanness of leprosy, he was sprinkled not only with blood, but with the flowing water of purification into which the blood had flowed, and was thus purified from his mortal uncleanness. Whereas one of the birds, however, had to lay down its life, and shed its blood for the person to be cleansed, the other was made into a symbol of the person to be cleansed by being bathed in the mixture of blood and water; and its release, to return to its fellows and into its nest, represented his deliverance from the ban of death which rested upon leprosy, and his return to the fellowship of his own nation. This signification of the rite serves to explain not only the appointment of birds for the purpose, since free unfettered movement in all directions could not be more fittingly represented by anything than by birds, which are distinguished from all other animals by their freedom and rapidity of motion, but also the necessity for their being alive and clean, viz., to set forth the renewal of life and purification; also the addition of cedar-wood, scarlet wool, and hyssop, by which the life-giving power of the blood mixed with living (spring) water was to be still further strengthened. The cedar-wood, on account of its antiseptic qualities (ἔχει ἄσηπτον ἡ κέδρος, Theodor. on Eze 17:22), was a symbol of the continuance of life; the coccus colour, a symbol of freshness of life, or fulness of vital energy; and the hyssop (βοτάνη ῥυπτική, herba humilis, medicinalis, purgandis pulmonibus apta: August. on Ps 51), a symbol of purification from the corruption of death. The sprinkling was performed seven times, because it referred to a readmission into the covenant, the stamp of which was seven; and it was made with a mixture of blood and fresh water, the blood signifying life, the water purification.
Lev 14:8
After this symbolical purification from the mortal ban of leprosy, the person cleansed had to purify himself bodily, by washing his clothes, shaving off all his hair - i.e., not merely the hair of his head and beard, but that of his whole body (cf. Lev 14:9), - and bathing in water; and he could then enter into the camp. But he had still to remain outside his tent for seven days, not only because he did not yet feel himself at home in the congregation, or because he was still to retain the consciousness that something else was wanting before he could be fully restored, but, as the Chaldee has explained it by adding the clause, et non accedat ad latus uxoris suae, that he might not defile himself again by conjugal rights, and so interrupt his preparation for readmission into fellowship with Jehovah.
Lev 14:9-12
The second act (Lev 14:9-20) effected his restoration to fellowship with Jehovah, and his admission to the sanctuary. It commenced on the seventh day after the first with a fresh purification; viz., shaving off all the hair from the head, the beard, the eyebrows - in fact, the whole body, - washing the clothes, and bathing the body. On the eighth day there followed a sacrificial expiation; and for this the person to be expiated was to bring two sheep without blemish, a ewe-lamb of a year old, three-tenths of an ephah of fine flour mixed with oil as a meat-offering, and a log (or one-twelfth of a hin, i.e., as much as six hens' eggs, or 1562 Rhenish cubic inches) of oil; and the priest was to present him, together with these gifts, before Jehovah, i.e., before the altar of burnt-offering. The one lamb was then offered by the priest as a trespass-offering, together with the log of oil; and both of these were waves by him. By the waving, which did not take place on other occasions in connection with sin-offerings and trespass-offerings, the lamb and oil were transferred symbolically to the Lord; and by the fat that these sacrificial gifts represented the offerer, the person to be consecrated to the Lord by means of them was dedicated to His service again, just as the Levites were dedicated to the Lord by the ceremony of waving (Num 8:11, Num 8:15). But a trespass-offering was required as the consecration-offering, because the consecration itself served as a restoration to all the rights of the priestly covenant nation, which had been lost by the mortal ban of leprosy.
(Note: Others, e.g., Riehm and Oehler, regard this trespass-offering also as a kind of mulcta, or satisfaction rendered for the fact, that during the whole period of his sickness, and so long as he was excluded from the congregation, the leper had failed to perform his theocratical duties, and Jehovah had been injured in consequence. But if this was the idea upon which the trespass-offering was founded, the law would necessarily have required that trespass-offerings should be presented on the recovery of persons who had been affected with diseased secretions; for during the continuance of their disease, which often lasted a long time, even as much as 12 years (Luk 8:43), they were precluded from visiting the sanctuary or serving the Lord with sacrifices, because they were unclean, and therefore could not perform their theocratical duties.)
Lev 14:13-14
After the slaying of the lamb in the holy place, as the trespass-offering, like the sin-offering, was most holy and belonged to the priest (see at Lev 7:6), the priest put some of its blood upon the tip of the right ear, the right thumb, and the great toe of the right foot of the person to be consecrated, in order that the organ of hearing, with which he hearkened to the word of the Lord, and those used in acting and walking according to His commandments, might thereby be sanctified through the power of the atoning blood of the sacrifice; just as in the dedication of the priests (Lev 8:24).
Lev 14:15-18
The priest then poured some oil out of the log into the hollow of his left hand, and dipping the finger of his right hand in the oil, sprinkled it seven times before Jehovah, i.e., before the altar of burnt-offering, to consecrate the oil to God, and sanctify it for further use. With the rest of the oil he smeared the same organs of the person to be consecrated which he had already smeared with blood, placing it, in fact, "upon the blood of the trespass-offering," i.e., upon the spots already touched with blood; he then poured the remainder upon the head of the person to be consecrated, and so made atonement for him before Jehovah. The priests were also anointed at their consecration, not only by the pouring of oil upon their head, but by the sprinkling of oil upon their garments (Lev 8:12, Lev 8:30). But in their case the anointing of their head preceded the consecration-offering, and holy anointing oil was used for the purpose. Here, on the contrary, it was ordinary oil, which the person to be consecrated had offered as a sacrificial gift; and this was first of all sanctified, therefore, by being sprinkled and poured upon the organs with which he was to serve the Lord, and then upon the head, which represented his personality. Just as the anointing oil, prepared according to divine directions, shadowed forth the power and gifts of the Spirit, with which God endowed the priests for their peculiar office in His kingdom; so the oil, which the leper about to be consecrated presented as a sacrifice out of his own resources, represented the spirit of life which he had received from God, and now possessed as his own. This property of his spirit was presented to the Lord by the priestly waving and sprinkling of the oil before Jehovah, to be pervaded and revived by His spirit of grace, and when so strengthened, to be not only applied to those organs of the person to be consecrated, with which he fulfilled the duties of his vocation as a member of the priestly nation of God, but also poured upon his head, to be fully appropriated to his person. And just as in the sacrifice the blood was the symbol of the soul, so in the anointing the oil was the symbol of the spirit. If, therefore, the soul was established in gracious fellowship with the Lord by being sprinkled with the atoning blood of sacrifice, the anointing with oil had reference to the spirit, which gives life to soul and body, and which was thereby endowed with the power of the Spirit of God. In this way the man cleansed from leprosy was reconciled to Jehovah, and reinstated in the covenant privileges and covenant grace.
Lev 14:19-20
It was not till all this had been done, that the priest could proceed to make expiation for him with the sin-offering, for which the ewe-lamb was brought, "on account of his uncleanness," i.e., on account of the sin which still adhered to him as well as to all the other members of the covenant nation, and which had come outwardly to light in the uncleanness of his leprosy; after which he presented his burnt-offering and meat-offering, which embodied the sanctification of all his members to the service of the Lord, and the performance of works well-pleasing to Him. The sin-offering, burnt-offering, and meat-offering were therefore presented according to the general instructions, with this exception, that, as a representation of diligence in good works, a larger quantity of meal and oil was brought than the later law in Num 15:4 prescribed for the burnt-offering.
Lev 14:21-32
In cases of poverty on the part of the person to be consecrated, the burnt-offering and sin-offering were reduced to a pair of turtle-doves or young pigeons, and the meat-offering to a tenth of an ephah of meal and oil; but no diminution was allowed in the trespass-offering as the consecration-offering, since this was the conditio sine qua non of reinstatement in full covenant rights. On account of the importance of all the details of this law, every point is repeated a second time in Lev 14:21-32.
