If there is among you any man who is not clean because of an accident at night, then he shall go outside the camp. He shall not come inside the camp.
And if any man's semen goes from him, then he shall wash all his flesh in water and be unclean until the evening.
And it shall be as evening turns, he shall wash with water. And when the sun is down, he shall come into the the middle of the camp.
When the army goes forth against your enemies, then keep yourself from every wicked thing.
And you surely shall keep clear of the cursed thing, lest you make yourselves cursed when you take of the cursed things, and make the camp of Israel a curse, and trouble it.
