Leviticus 12:2-4

²“Tell this to the Israeli people: If a woman gives birth to a son, she must be avoided for seven days, like she must be avoided when she is menstruating each month.

³The baby son must be circumcised on the eighth day after he is born.

⁴Then the woman must wait 33 days to be purified from her bleeding during childbirth. She must not touch anything that is sacred or enter the Sacred Tent area until that time is ended.
