Leviticus 12:5

two weeks … sixty-six days: The total is eighty days. This is double the purification time needed for a son's birth (see also Leviticus 27:2–7).

These verses explain the rules about childbirth. Any bodily discharge, including blood, was "abnormal" because it weakened the person and made them ceremonially unclean (see study notes on Leviticus 5:3; 11:1–15:33). These verses focus on the discharge that comes with childbirth, not childbirth itself (12:2, 5, 7). The uncleanness was not sinful unless they ignored it and it came into contact with something holy (see 5:2–3).

The law here pronounces women lying-in ceremonially unclean. The Jews say, "The law extended even to an abortion, if the child was so formed as that the sex was distinguishable." 1. There was some time of strict separation immediately after the birth, which continued seven days for a son and fourteen for a daughter, Lev 12:2, Lev 12:5. During these days she was separated from her husband and friends, and those that necessarily attended her were ceremonially unclean, which was one reason why the males were not circumcised till the eighth day, because they participated in the mother's pollution during the days of her separation. 2. There was also a longer time appointed for their purifying; thirty-three days more (forty in all) if the birth were a male, and double that time if a female, Lev 12:4, Lev 12:5. During this time they were only separated from the sanctuary and forbidden to eat of the passover, or peace-offerings, or, if a priest's wife, to eat of any thing that was holy to the Lord. Why the time of both those was double for a female to what it was for a male I can assign no reason but the will of the Law-maker; in Christ Jesus no difference is made of male and female, Gal 3:28; Col 3:11. But this ceremonial uncleanness which the law laid women in child-bed under was to signify the pollution of sin which we are all conceived and born in, Psa 51:5. For, if the root be impure, so is the branch, Who can bring a clean thing out of an unclean? If sin had not entered, nothing but purity and honour had attended all the productions of that great blessing, Be fruitful and multiply; but now that the nature of man is degenerated the propagation of that nature is laid under these marks of disgrace, because of the sin and corruption that are propagated with it, and in remembrance of the curse upon the woman that was first in the transgression. That in sorrow (to which it is here further added in shame) she should bring forth children. And the exclusion of the woman for so many days from the sanctuary, and all participation of the holy things, signified that our original corruption (that sinning sin which we brought into the world with us) would have excluded us for ever from the enjoyment of God and his favours if he had not graciously provided for our purifying.

The blood of her purifying - A few words will make this subject sufficiently plain.
1. God designs that the human female should bring forth children.
2. That children should derive, under his providence, their being, all their solids and all their fluids, in a word, the whole mass of their bodies, from the substance of the mother.
3. For this purpose he has given to the body of the female an extra quantity of blood and nutritious juices.
4. Before pregnancy this superabundance is evacuated at periodical times.
5. In pregnancy, that which was formerly evacuated is retained for the formation and growth of the fetus, or the general strengthening of the system during the time of pregnancy.
6. After the birth of the child, for seven or fourteen days, more or less according to certain circumstances, that superabundance, no longer necessary for the growth of the child as before, continues to be evacuated: this was called the time of the female's purification among the Jews.
7. When the lacerated vessels are rejoined, this superfluity of blood is returned into the general circulation, and, by a wise law of the Creator, becomes principally useful to the breasts, and helps in the production of milk for the nourishment of the new-born infant.
8. And thus it continues till the weaning of the child, or renewed pregnancy takes place. Here is a series of mercies and wise providential regulations which cannot be known without being admired, and which should be known that the great Creator and Preserver may have that praise from his creatures which his wonderful working demands.
The term purifying here does not imply that there is any thing impure in the blood at this or the other times referred to above; on the contrary, the blood is pure, perfectly so, as to its quality, but is excessive in quantity for the reasons above assigned. The idle tales found in certain works relative to the infectious nature of this fluid, and of the female in such times are as impious as they are irrational and absurd.

But if she bear a maid child,.... A daughter, whether born alive or dead, if she goes with it her full time:

then she shall be unclean two weeks; or fourteen days running; and on the fifteenth day be free or loosed, as the Targum of Jonathan, just as long again as for a man child:

as in her separation; on account of her monthly courses; the sense is, that she should be fourteen days, to all intents and purposes, as unclean as when these are upon her:

and she shall continue in the blood of her purifying sixty and six days; which being added to the fourteen make eighty days, just as many more as in the case of a male child; the reason of which, as given by some Jewish writers, is, because of the greater flow of humours, and the corruption of the blood through the birth of a female than of a male: but perhaps the truer reason may be, what a learned man (p) suggests, that a male infant circumcised on the eighth day, by the profusion of its own blood, bears part of the purgation; wherefore the mother, for the birth of a female, must suffer twice the time of separation; the separation is finished within two weeks, but the purgation continues sixty six days; a male child satisfies the law together, and at once, by circumcision; but an adult female bears both the purgation and separation every month. According to Hippocrates (q), the purgation of a new mother, after the birth of a female, is forty two days, and after the birth of a male thirty days; so that it should seem there is something in nature which requires a longer time for purifying after the one than after the other, and which may in part be regarded by this law; but it chiefly depends upon the sovereign will of the lawgiver. The Jews do not now strictly observe this. Buxtorf (r) says, the custom prevails now with them, that whether a woman bears a male or a female, at the end of forty days she leaves her bed, and returns to her husband; but Leo of Modena relates (s), that if she bears a male child, her husband may not touch her for the space of seven weeks; and if a female, the space of three months; though he allows, in some places, they continue separated a less while, according as the custom of the place is.

The time in both particulars is double to the former, not so much from natural causes, because the purifications in female births are longer and slower, which if it were true, yet doth not extend to any such time as here is mentioned, as for moral reasons; either to be as a blot upon that sex for being the first in man’ s transgression, , or to put an honour upon the sacrament of circumcision, which being administered to the males, did put an end to that pollution sooner than otherwise had been; or to show the privilege of the man above the woman, and that the women were to be purified, sanctified, and saved by one of the other sex, even by the man Christ Jesus, without whom they should have still continued in their impurity.

But if she had given birth to a girl, she was to be unclean two weeks (14 days), as in her menstruation, and then after that to remain at home 66 days. The distinction between the seven (or fourteen) days of the "separation for her infirmity," and the thirty-three (or sixty-six) days of the "blood of her purifying," had a natural ground in the bodily secretions connected with child-birth, which are stronger and have more blood in them in the first week (lochia rubra) than the more watery discharge of the lochia alba, which may last as much as five weeks, so that the normal state may not be restored till about six weeks after the birth of the child. The prolongation of the period, in connection with the birth of a girl, was also founded upon the notion, which was very common in antiquity, that the bleeding and watery discharge continued longer after the birth of a girl than after that of a boy (Hippocr. Opp. ed. Khn. i. p. 393; Aristot. h. an. 6, 22; 7, 3, cf. Burdach, Physiologie iii. p. 34). But the extension of the period to 40 and 80 days can only be accounted for from the significance of the numbers, which we meet with repeatedly, more especially the number forty (see at Exo 24:18).
