The Book of Leviticus

And the Lord spoke to Moses, saying:

Speak to the children of Israel, and thou shalt say to them: If a woman having received seed shall bear a man child, she shall be unclean seven days, according to the days of separation of her flowers.

And on the eighth day the infant shall be circumcised:

But she shall remain three and thirty days in the blood of her purification. She shall touch no holy thing: neither shall she enter into the sanctuary, until the days of her purification, be fulfilled.

But if she shall bear a maid child, she shall be unclean two weeks, according to the custom of her monthly courses. And she shall remain in the blood of her purification sixty-six days.

And when the days of her purification are expired, for a son, or for a daughter, she shall bring to the door of the tabernacle of the testimony, a lamb of a year old for a holocaust, and a young pigeon or a turtle for sin: and shall deliver them to the priest.

Who shall offer them before the Lord, and shall pray for her: and so she shall be cleansed from the issue of her blood. This is the law for her that beareth a man child or a maid child.

And if her hand find not sufficiency, and she is not able to offer a lamb, she shall take two turtles, or two young pigeons, one for a holocaust, and another for sin: and the priest shall pray for her, and so she shall be cleansed.
