Leviticus 15:14-19

¹⁴And on the eighth day he shall take to him two turtle-doves, or two young pigeons, and come before the LORD to the door of the tabernacle of the congregation, and give them to the priest:

¹⁵And the priest shall offer them, the one for a sin-offering, and the other for a burnt-offering; and the priest shall make an atonement for him before the LORD for his issue.

¹⁶And if any man's seed of copulation shall go from him, then he shall wash all his flesh in water, and be unclean until the evening.

¹⁷And every garment, and every skin on which is the seed of copulation, shall be washed with water, and be unclean until the evening.

¹⁸The woman also with whom man shall lie with seed of copulation, they shall both bathe themselves in water, and be unclean until the evening.

¹⁹And if a woman shall have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whoever toucheth her shall be unclean until the evening.
