Leviticus 15:13-15

13“When a man’s discharge stops, he must wait seven days to be cleansed. He must wash his clothes and his body in fresh water. Then he will be clean.

14On the eighth day he must take two mourning doves or two pigeons and come into the Lord’s presence at the entrance to the tent of meeting. He will give these birds to the priest.

15The priest will sacrifice one as an offering for sin and the other as a burnt offering. So in the Lord’s presence, the priest will make peace with the Lord for the man who had a discharge.
