Leviticus 12:2-5

2“Speak to Bnei-Yisrael, instructing: If a woman conceives and bears a male child, then she will be unclean for seven days, as in the days of her niddah she will be unclean.

3In the eighth day the flesh of his foreskin is to be circumcised.

4She must wait during the blood of purification for 33 days. She is not to touch any holy thing, nor come into the Sanctuary, until the days of her purifying are completed.

5But if she bears a female child, then she will be unclean for two weeks, as in her niddah , and she is to wait in the blood of purification for 66 days.
