Say to the children of Israel, If a woman is with child and gives birth to a male child, she will be unclean for seven days, as when she is unwell.
Leviticus 12:2
And if she has not money enough for a lamb, then let her take two doves or two young pigeons, one for a burned offering and the other for a sin-offering, and the priest will take away her sin and she will be clean,
Leviticus 12:8
