Leviticus 12:2-5

2“Tell the Israelites, ‘When a woman produces offspring and bears a male child, she will be unclean seven days, as she is unclean during the days of her menstruation.

3On the eighth day the flesh of his foreskin must be circumcised.

4Then she will remain thirty-three days in blood purity. She must not touch anything holy and she must not enter the sanctuary until the days of her purification are fulfilled.

5If she bears a female child, she will be impure fourteen days as during her menstrual flow, and she will remain sixty-six days in blood purity.
