Speak unto the children of Israel, saying, If a woman have conceived seed, and born a man child: then she shall be unclean {a} seven days; according to the days of the separation for her infirmity shall she be unclean.

(a) So that her husband for that time could not have relations with her.

Wesley's Notes

12:2 Seven days - Not for any filthiness which was either in the conception, or in bringing forth, but to signify the universal and deep pollution of man's nature, even from the birth, and from the conception. Seven days or thereabouts, nature is employed in the purgation of most women. Her infirmity - Her monthly infirmity. And it may note an agreement therewith not only in the time, Lev 15:19, but in the degree of uncleanness.

Jamieson-Fausset-Brown Bible Commentary

2. If a woman, &c.-The mother of a boy was ceremonially unclean for a week, at the end of which the child was circumcised (Ge 17:12; Ro 4:11-13); the mother of a girl for two weeks (Le 12:5)-a stigma on the sex (1Ti 2:14, 15) for sin, which was removed by Christ; everyone who came near her during that time contracted a similar defilement. After these periods, visitors might approach her though she was still excluded from the public ordinances of religion [Le 12:4].

Matthew Henry's Concise Commentary

12:1-8 Ceremonial purification. - After the laws concerning clean and unclean food, come the laws concerning clean and unclean persons. Man imparts his depraved nature to his offspring, so that, excepting as the atonement of Christ and the sanctification of the Spirit prevent, the original blessing, Increase and multiply, Ge 1:28, is become to the fallen race a direful curse, and communicates sin and misery. Let those women who have received mercy from God in child-bearing, with all thankfulness own God's goodness to them; and this shall please the Lord better than sacrifices.

Matthew Henry's Whole Bible Commentary

Chapter 12

After the laws concerning clean and unclean food come the laws concerning clean and unclean persons; and the first is in this chapter concerning the ceremonial uncleanness of women in child-birth (v. 1-5). And concerning their purification from that uncleanness (v. 6, etc.).

Verses 1-5

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, v. 2, 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, v. 4, 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, Ps. 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.
