Leviticus 12:2-6

12:2 “Tell the Israelites, ‘When a woman produces offspring and bears a male child, she will be unclean seven days, as she is unclean during the days of her menstruation. 12:3 On the eighth day the flesh of his foreskin must be circumcised. 12:4 Then she will remain thirty-three days in blood purity. She must not touch anything holy and she must not enter the sanctuary until the days of her purification are fulfilled. 12:5 If she bears a female child, she will be impure fourteen days as during her menstrual flow, and she will remain sixty-six days in blood purity.

12:6 “‘When the days of her purification are completed for a son or for a daughter, she must bring a one year old lamb for a burnt offering and a young pigeon or turtledove for a sin offering to the entrance of the Meeting Tent, to the priest.
