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.

If a woman have conceived - In the extent mentioned here the ordinances of this chapter have little relation to us: and to inquire into their physical reasons, as far as they related to the Jews, could afford but little edification; and to make such a subject sufficiently plain would require such minute examination and circumstantial detail as could scarcely be proper for several readers. All that is necessary to be said the reader will find on Lev 12:4.

Speak unto the children of Israel,.... For this law only concerned them, and not other nations of the world:

if a woman have conceived seed; by lying with a man, and so becomes pregnant, and goes on with her pregnancy until she brings forth a child. The Jews from hence gather, that this law respects abortions; that if a woman has conceived and miscarries, eighty one days after the birth of a female, and forty one after a male, she must bring her offering (m); but the law seems only to regard such as are with child, and proceed to the due time of childbirth, whether then the child is born alive or dead:

and born a man child; which is, generally speaking, not only matter of joy to the mother, but to the whole family, see Joh 16:21 then she shall be unclean seven days; be separate from all company, except those whose presence is necessary to take care of her in her circumstances, and do what is proper for her, and even these became ceremonially unclean thereby; yea, her husband was not permitted to sit near her, nor to eat and drink with her:

according to the days of the separation for her infirmity shall she be unclean; the same number of days, even seven, she was unclean on account of childbirth, as she was for her monthly courses, called here an infirmity or sickness, incident to all females when grown up, at which time they were separate from all persons; and the case was the same with a new mother; see Lev 15:14.
