Leviticus 12:1-4

Then the LORD spoke to Moses, saying, “Speak to the sons of Israel, saying: ‘ W hen a woman gives birth and bears a male child, then she shall be unclean for seven days, as in the days of her menstruation she shall be unclean. On the eighth day the flesh of his foreskin shall be circumcised. Then she shall remain in the blood of her purification for thirty-three days; she shall not touch any consecrated thing, nor enter the sanctuary until the days of her purification are completed.
