Leviticus 15:13-15

¹³“‘When he who has a discharge is cleansed of his discharge, then he shall count to himself seven days for his cleansing, and wash his clothes; and he shall bathe his flesh in running water, and shall be clean.

¹⁴“‘On the eighth day he shall take two turtledoves, or two young pigeons, and come before the LORD to the door of the Tent of Meeting, and give them to the priest.

¹⁵The priest shall offer them, the one for a sin offering, and the other for a burnt offering. The priest shall make atonement for him before the LORD for his discharge.
