Leviticus 12:1

“Speak to the children of Israel, saying, ‘If a woman conceives, and bears a male child, then she shall be unclean seven days; as in the days of her monthly period she shall be unclean.

In the eighth day the flesh of his foreskin shall be circumcised.

She shall continue in the blood of purification thirty-three days. She shall not touch any holy thing, nor come into the sanctuary, until the days of her purifying are completed.
