Leviticus 12:1-4

Then the Lord spoke to Moses, saying,

“Speak to the sons of Israel, saying: ‘When a woman gives birth and delivers a male child, then she shall be unclean for seven days; as she is in the days of her menstruation, she shall be unclean.

Then on the eighth day the flesh of his foreskin shall be circumcised.

And she shall stay at home in her condition of blood purification for thirty-three days; she shall not touch any consecrated thing, nor enter the sanctuary until the days of her purification are completed.
