Leviticus 12:1-4

1The Lord spoke to Moses, saying,

2"Speak to the people of Israel, saying, 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 anything holy, nor come into the sanctuary, until the days of her purifying are completed.
