If one of your men is unclean because of a nocturnal emission, he is to go outside the camp and stay there.
“ ‘When a man has an emission of semen, he must bathe his whole body with water, and he will be unclean till evening.
But as evening approaches he is to wash himself, and at sunset he may return to the camp.
When you are encamped against your enemies, keep away from everything impure.
But keep away from the devoted things, so that you will not bring about your own destruction by taking any of them. Otherwise you will make the camp of Israel liable to destruction and bring trouble on it.
