Leviticus 12:3 Meaning and Commentary

Leviticus 12:3

And in the eighth day the flesh of his foreskin shall be
circumcised.
] Or the foreskin of his flesh, that is, of the man child born according to the law, ( Genesis 17:12 ) and this seems to furnish out a reason why a male child was not circumcised before the eighth day, and why it was then, because before that its mother was in her separation and uncleanness, and then was freed from it; and so the Targum of Jonathan. The circumcision of a male child on the eighth day was religiously observed, and even was not omitted on account of the sabbath, when the eighth day happened to be on that, (See Gill on John 7:22) (See Gill on John 7:23). It is an observation of Aben Ezra on this place, that the wise men say "in the day", and not in the night, lo, he that is born half an hour before the setting of the sun is circumcised after six days and a half, for the day of the law is not from time to time.

Leviticus 12:3 In-Context

1 And the Lord spake to Moses, and said,

2 Speak thou to the sons of Israel, and thou shalt say to them, If a woman, when she hath received seed, childeth a knave child, she shall be unclean by seven days, by the days of her separating of corruptible blood, that runneth from her by months; (Speak thou to the Israelites, and thou shalt say to them, If a woman, when she hath received seed, beareth a boy, she shall be unclean for seven days, as she is in the days of her separation for the corrupt blood that runneth from her every month;)

3 and the young child shall be circumcised in the eighth day. (and the young boy shall be circumcised on the eighth day.)

4 Soothly she shall dwell three and thirty days in the blood of her purifying; she shall not touch any holy thing, neither she shall enter into the saintuary, till the days of her cleansing be [ful]filled.

5 Soothly if she childeth a female, she shall be unclean (for) two weeks, (as she is) by the custom of [the] flowing (out) of unclean blood, and threescore and six days she shall dwell in the blood of her cleansing.
