Toward evening, he shall bathe in water; then, when the sun has set, he may come back into the camp.
When a man has an emission of semen, he shall bathe his whole body in water and be unclean until evening.
If one of you becomes unclean because of a nocturnal emission, he shall go outside the camp; he shall not come back into the camp.
Outside the camp you shall have a place set aside where you shall go.
