Leviticus 12

Yahweh spoke to Moses, saying,

Speak to the children of Israel, saying, If a woman conceive seed, and bear a man-child, then she shall be unclean seven days; as in the days of the impurity of her sickness shall she be unclean.

In the eighth day the flesh of his foreskin shall be circumcised.

She shall continue in the blood of [her] purifying three and thirty days; she shall touch no holy thing, nor come into the sanctuary, until the days of her purifying be fulfilled.

But if she bear a maid-child, then she shall be unclean two weeks, as in her impurity; and she shall continue in the blood of [her] purifying sixty-six days.

When the days of her purifying are fulfilled, for a son, or for a daughter, she shall bring a lamb a year old for a burnt offering, and a young pigeon, or a turtle-dove, for a sin-offering, to the door of the tent of meeting, to the priest:

and he shall offer it before Yahweh, and make atonement for her; and she shall be cleansed from the fountain of her blood. This is the law for her who bears, whether a male or a female.

If her means isn`t sufficient for a lamb, then she shall take two turtle-doves, or two young pigeons; the one for a burnt offering, and the other for a sin-offering: and the priest shall make atonement for her, and she shall be clean.
