Adonoy spoke to Moshe saying:

Speak to Bnei Yisroel, saying, when a woman conceives and gives birth to a male child she will be ritually unclean for seven days; as the days of her menstrual flow [the state of her impure ‘separation’], she will be unclean.

On the eighth day, the flesh of his foreskin shall be circumcised.

For thirty-three days she will remain [in the status] that the blood [she sees] is ritually pure. She shall not touch anything holy and she shall not come into the Sanctuary, until the days of her purity are completed.

If she gives birth to a female she will be unclean for two weeks [fourteen days] as during her menstruation [‘separation’]. For sixty-six days she will remain [in the status] that the blood [she sees] is ritually pure.

When the days of her purification are completed, be it for a son or for a daughter, she shall bring a lamb, in its first year, as a burnt-offering and a young pigeon or a turtledove as a sin-offering, to the entrance of the Tent of Meeting, to the kohein.

He will bring it before Adonoy and atone for her and she will be cleansed from the source [impurity] of her blood; this is the law regarding the woman who gives birth to a male or to a female.

If she cannot afford [to acquire] a lamb she shall take two turtledoves or two young pigeons; one as a burnt-offering and one as a sin-offering. The kohein will atone for her and she will be cleansed.
