Leviticus 15:13-15

13“‘When the man with the discharge becomes clean from his discharge he is to count off for himself seven days for his purification, and he must wash his clothes, bathe in fresh water, and be clean.

14Then on the eighth day he is to take for himself two turtledoves or two young pigeons, and he is to present himself before the Lord at the entrance of the Meeting Tent and give them to the priest,

15and the priest is to make one of them a sin offering and the other a burnt offering. So the priest is to make atonement for him before the Lord for his discharge.
