Leviticus 12:1-4

Then the LORD spoke to Moses, saying, “Speak to the children of Israel, saying, ‘ I f a woman conceives and gives birth to a male child, she shall be [ceremonially] unclean for seven days, unclean as during her monthly period. On the eighth day the flesh of the male child’s foreskin shall be circumcised. Then she shall remain [intimately separated] thirty-three days to be purified from the blood; she shall not touch any consecrated thing nor enter the [courtyard of the] sanctuary until the days of her purification are over.
