Deuteronomy 23:9-14

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.

¹² Choose a place outside the camp where people may go to relieve themselves. ¹³ Carry a tent peg with you, and when you relieve yourself, dig a hole and cover up your dung. ¹⁴ The Lord your God moves around through your camp to protect you and to defeat your enemies for you, so the camp must be holy. He must not see anything unclean among you so that he will not leave you.
