Numbers 5:4

• Modern Western people may find it difficult to understand the Old Testament laws of purity. Today, things like skin diseases, bodily discharges, or contact with a dead body are viewed mainly as health concerns. But in the Old Testament, the main concern was protecting God’s holiness from ceremonial uncleanness (see Leviticus 11–15).

  The community had to keep the camp holy. Nothing unclean could touch what belonged to the Lord (Numbers 5:2–3). They had to choose between having God in the camp or allowing a ceremonially polluted person stay. Both could not remain (5:3).

• The importance of purity continues from Leviticus and Numbers to the book of Revelation. Nothing ceremonially unclean will enter the New Jerusalem where God lives (see study note on Revelation 21:27). In the New Testament, impurity most often refers to what is morally impure (Acts 10:28; Ephesians 5:5; 1 Thessalonians 2:3; 4:7).

These laws speak about cleanliness, repayment, and staying faithful in marriage.

Here is, I. A command for the purifying of the camp, by turning out from within its lines all those that were ceremonially unclean, by issues, leprosies, or the touch of dead bodies, until they were cleansed according to the law, Num 5:2, Num 5:3.
1. These orders are executed immediately, Num 5:4. (1.) The camp was now newly-modelled and put in order, and therefore, to complete the reformation of it, it is next to be cleansed. Note, The purity of the church must be as carefully consulted and preserved as the peace and order of it. It is requisite, not only that every Israelite be confined to his own standard, but that every polluted Israelite be separated from it. The wisdom from above is first pure, then peaceable. (2.) God's tabernacle was now fixed in the midst of their camp, and therefore they must be careful to keep it clean. Note, The greater profession of religion any house or family make the more they are obliged to put away iniquity far from their tabernacle, Job 22:23. The person, the place, in the midst of which God dwells, must not be defiled; for, if it be, he will be affronted, offended, and provoked to withdraw, Co1 3:16, Co1 3:17.
2. This expulsion of the unclean out of the camp was to signify, (1.) What the governors of the church ought to do: they must separate between the precious and the vile, and purge out scandalous persons, as old leaven (Co1 5:8, Co1 5:13), lest others should be infected and defiled, Heb 12:15. It is for the glory of Christ and the edification of his church that those who are openly and incorrigibly profane and vicious should be put out and kept from Christian communion till they repent. (2.) What God himself will do in the great day: he will thoroughly purge his floor, and gather out of his kingdom all things that offend. As here the unclean were shut out of the camp, so into the new Jerusalem no unclean thing shall enter, Rev 21:27.
II. A law concerning restitution, in case of wrong done to a neighbour. It is called a sin that men commit (Num 5:6), because it is common among men; a sin of man, that is, a sin against man, so it is thought it should be translated and understood. If a man overreach or defraud his brother in any matter, it is to be looked upon as a trespass against the Lord, who is the protector of right, the punisher of wrong, and who strictly charges and commands us to do justly. Now what is to be done when a man's awakened conscience charges him with guilt of this kind, and brings it to his remembrance though done long ago? 1. He must confess his sin, confess it to God, confess it to his neighbour, and so take shame to himself. If he have denied it before, though it go against the grain to own himself in a lie, yet he must do it; because his heart was hardened he denied it, therefore he has no other way of making it appear that his heart is now softened but by confessing it. 2. He must bring a sacrifice, a ram of atonement, Num 5:8. Satisfaction must be made for the offence done to God, whose law is broken, as well as for the loss sustained by our neighbour; restitution in this case is not sufficient without faith and repentance. 3. Yet the sacrifices would not be accepted till full amends were made to the party wronged, not only the principal, but a fifth part added to it, Num 5:7. It is certain that while that which is got by injustice is knowingly retained in the hands the guilt of the injustice remains upon the conscience, and is not purged by sacrifice nor offering, prayers not tears, for it is one and the same continued act of sin persisted in. This law we had before (Lev 6:4), and it is here added that if the party wronged was dead, and he had no near kinsman who was entitled to the debt, or if it was any way uncertain to whom the restitution should be made, this should not serve for an excuse to detain what was unjustly gotten; to whomsoever it pertained, it was certainly none of his that got it by sin, and therefore it must be given to the priest, Num 5:8. If there were any that could make out a title to it, it must not be given to the priest (God hates robbery for burnt-offerings); but, if there were not, then it lapsed to the great Lord (ob defectum sanguinis - for want of issue), and the priests were his receivers. Note, Some work of piety or charity is a piece of necessary justice to be done by those who are conscience to themselves that they have done wrong, but know not how otherwise to make restitution; what is not our property will never be our profit.
III. A general rule concerning hallowed things given upon this occasion, that, whatever was given to the priest, his it shall be, Num 5:9, Num 5:10. 1. He that gave it was not to receive his gift again upon any pretence whatsoever. This law ratifies and confirms all grants for pious uses, that people might not give things to the priests in a fit of zeal, and then recall them in a fit of vexation. 2. The other priests should not come in sharers with that priest who then officiated, and to whom the hallowed thing, whatever it was, was given. Let him that was most ready and diligent in attending fare the better for it: if he do the work, let him have the pay, and much good may it do him.

Numbers 5:1-3

1. And the Lord spake unto Moses, saying,

1. Et loquutus est Jehova ad Mosen, dicendo:

2. Command the children of Israel, that they put out of the camp every leper, and every one that hath an issue, and whosoever is defiled by the dead:

2. Praecipe filiis Israel ut ejiciant e castris omnem leprosum, omnem seminifluum, et omnem immundum super anima.

3. Both male and female shall ye put out, without the camp shall ye put them; that they defile not their camps, in the midst whereof I dwell.

3. Tam masculum quam faeminam ejicietis: extra castra ejicietis eos, ne contaminent castra sua, quia ego habito in medio eorum.

2. Command the children of Israel. This passage clearly shews that God, in desiring the lepers to be put out of the camp, was not acting as a physician by any means, and merely consulting the health of the people: but that by this external rite and ceremony He exercised them in the pursuit of purity; for, by joining with the lepers those who had an issue, [2] and who were defiled by the dead, He instructs the people simply to keep away from all uncleanness. The reason, which follows, confirms this, -- "that they defile not their camps, in the midst whereof He dwells." It is just as if He had said, that all the habitations of His elect people were parts of His sanctuary, which it was a shame to defile with any pollution. For we know what license men give themselves in corrupting [3] the service of God, by mixing, as the proverb says, sacred things with profane. Thus we see that the very worst of men boast themselves to be anything but the least zealous of His worshipers, and spare not to lift up polluted hands, although God so sternly repudiates them. It was, then, profitable that the ancient people should be reminded by this visible proof, that all those who are defiled cannot duly serve God, but that they rather pollute. with their filthiness what is otherwise holy, and thus grossly abuse religious exercises; and again, that they ought not tobe tolerated in the holy congregation, lest their infection should spread to others. Let us now briefly examine [2]Leviticus 13

And the children of Israel did so, and put them without the camp,.... Aben Ezra observes, that this was done immediately before they journeyed, and that those that were defiled journeyed between the standard of Ephraim and the standard of Dan; but this, he says, was by way of conjecture, since it is not expressed:

as the Lord spake unto Moses, so did the children of Israel; they were obedient in this particular.

Removal of Unclean Persons out of the Camp. - As Jehovah, the Holy One, dwelt in the midst of the camp of His people, those who were affected with the uncleanness of leprosy (Lev 13), of a diseased flux, or of menstruation (Lev 15:2., Num 15:19.), and those who had become unclean through touching a corpse (Num 19:11., cf. Lev 21:1; Lev 22:4), whether male or female, were to be removed out of the camp, that they might not defile it by their uncleanness. The command of God, to remove these persons out of the camp, was carried out at once by the nation; and even in Canaan it was so far observed, that lepers at any rate were placed in special pest-houses outside the cities (see at Lev 13:45-46).
