Leviticus 12:2-4

²Any woman who becomes pregnant and has a boy, she will be unclean for one week, in the same way that she is unclean during her period.

³The boy's foreskin must be circumcised on the eighth day.

⁴The woman must wait a further thirty-three days for the purification of her bleeding. She is not allowed to touch anything holy, and she is not allowed to enter the sanctuary until her time of purification is finished.
