Leviticus 12

And YHWH speaks to Moses, saying,

“Speak to the sons of Israel, saying, A woman when she gives seed, and has borne a male, then she has been unclean [for] seven days; she is unclean according to the days of separation for her sickness;

and in the eighth day the flesh of his foreskin is circumcised;

and she abides in the blood of her cleansing [for] thirty-three days; she does not come against any holy thing, and she does not go into the sanctuary, until the fullness of the days of her cleansing.

And if she bears a female, then she has been unclean [for] two weeks, as in her separation; and she abides by the blood of her cleansing [for] sixty-six days.

And in the fullness of the days of her cleansing for son or for daughter she brings in a lamb, a son of a year, for a burnt-offering, and a young pigeon or a turtle-dove for a sin-offering, to the opening of the Tent of Meeting, to the priest;

and he has brought it near before YHWH, and has made atonement for her, and she has been cleansed from the fountain of her blood; this [is] the law of her who is bearing, in regard to a male or to a female.

And if her hand does not find the sufficiency of a sheep, then she has taken two turtle-doves or two young pigeons, one for a burnt-offering and one for a sin-offering, and the priest has made atonement for her, and she has been cleansed.”
