Deuteronomy 23:9-14

Persons Excluded from the Assembly

⁹“When you go out as an army against your enemies, you shall be on guard against every evil thing.

¹⁰“If there is among you any man who is unclean because of a nocturnal emission, then he must go outside the camp; he may not reenter the camp. ¹¹But when evening approaches, he shall bathe himself with water, and at sundown he may reenter the camp.

¹²“You shall also have a place allocated outside the camp, so that you may go out there to relieve yourself, ¹³and you shall have a spade among your tools, and it shall be when you sit down outside, you shall dig with it and shall turn and cover up your excrement. ¹⁴Since the Lord your God walks in the midst of your camp to save you and to defeat your enemies before you, your camp must be holy; so He must not see anything indecent among you or He will turn away from you.
