Lk 2.22-24. The Lord said to Moses, 2“Say to the people of Israel, If a woman conceives, and bears a male child, then she shall be unclean seven days; as at the time of her menstruation, she shall be unclean. 3And on the eighth day the flesh of his foreskin shall be circumcised. 4Then she shall continue for thirty-three days in the blood of her purifying; she shall not touch any hallowed thing, nor come into the sanctuary, until the days of her purifying are completed. 5But if she bears a female child, then she shall be unclean two weeks, as in her menstruation; and she shall continue in the blood of her purifying for sixty-six days.
6“And when the days of her purifying are completed, whether for a son or for a daughter, she shall bring to the priest at the door of the tent of meeting a lamb a year old for a burnt offering, and a young pigeon or a turtledove for a sin offering, 7and he shall offer it before the Lord, and make atonement for her; then she shall be clean from the flow of her blood. This is the law for her who bears a child, either male or female. 8And if she cannot afford a lamb, then she shall take two turtledoves or two young pigeons, 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.”
