Leviticus 12:2-4

²Speak to the children of Israel, and thou shalt say to them, Whatsoever woman shall have conceived and born a male child shall be unclean seven days, she shall be unclean according to the days of separation for her monthly courses.

³And on the eighth day she shall circumcise the flesh of his foreskin.

⁴And for thirty-three days she shall continue in her unclean blood; she shall touch nothing holy, and shall not enter the sanctuary, until the days of her purification be fulfilled.
