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 Leviticus 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 John 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 Leviticus 15:14.

(m) Misn. Ceritot, c. 1. sect. 6. Maimon. & Bartenora, in ib.

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.

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.

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].

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.
