The First Book of Moses, Commonly Called Leviticus (WEB)
12: 1Yahweh spoke to Moses, saying, 12:2"Speak to the children of Israel, saying, 'If a woman conceives, and bears a male child, then she shall be unclean seven days; as in the days of her monthly period she shall be unclean. 12:3In the eighth day the flesh of his foreskin shall be circumcised. 12:4She shall continue in the blood of purification thirty-three days. She shall not touch any holy thing, nor come into the sanctuary, until the days of her purifying are completed. 12:5But if she bears a female child, then she shall be unclean two weeks, as in her period; and she shall continue in the blood of purification sixty-six days.
12:6"'When the days of her purification are completed, for a son, or for a daughter, she shall bring to the priest at the door of the Tent of Meeting, a year old lamb for a burnt offering, and a young pigeon, or a turtledove, for a sin offering: 12:7and 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. 12:8If she cannot afford a lamb, then
she shall take two turtledoves, 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.'"
