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 Jehovah speaketh unto Moses, saying,
2 `Speak unto the sons of Israel, saying, A woman when she giveth seed, and hath born a male, then she hath been unclean seven days, according to the days of separation for her sickness she is unclean;
3 and in the eighth day is the flesh of his foreskin circumcised;
4 and thirty and three days she doth abide in the blood of her cleansing; against any holy thing she doth not come, and unto the sanctuary she doth not go in, till the fulness of the days of her cleansing.
5 `And if a female she bear, then she hath been unclean two weeks, as in her separation; and sixty and six days she doth abide for the blood of her cleansing.
