Leviticus 12:1-5 (KJV1769):
1 And the LORD spake unto Moses, saying,
2 Speak unto the children of Israel, saying, If a woman
have conceived seed, and born a man child:
then she shall be unclean seven days;
according
to the days of the separation for her infirmity
shall she be unclean.
3
And in the eighth day the flesh of his foreskin
shall be circumcised.
Luke 2:21-24 (KJV1769):
And
when eight days were accomplished for the circumcising
of the child, his name was called JESUS,
which was so named of the angel before he was conceived
in the womb.
22 And
when the days of her purification according to
the law of Moses were accomplished, they brought him
to Jerusalem, to present him to the Lord;
23 (As it is written in the law of the Lord, Every
male that openeth the womb shall be called holy to the Lord

24 And to offer a sacrifice according to that which
is said in the law of the Lord, A pair of turtledoves,
or two young pigeons.
