Leviticus 15:16

“‘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.

“‘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.

The 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.

Every garment and every skin which the semen is on shall be washed with water, and be unclean until the evening.

If a man lies with a woman and there is an emission of semen, they shall both bathe themselves in water, and be unclean until the evening.

“‘If a woman has a discharge, and her discharge in her flesh is blood, she shall be in her impurity seven days. Whoever touches her shall be unclean until the evening.
