Deuteronomy 23:9-11

New Century Version

Keeping the Camp Clean

⁹ When you are camped in time of war, keep away from unclean things. ¹⁰ If a man becomes unclean during the night, he must go outside the camp and not come back. ¹¹ But when evening comes, he must wash himself, and at sunset he may come back into the camp.
