Deuteronomy 23:12

¹⁰And if thou shouldest go forth to engage with thine enemies, then thou shalt keep thee from every wicked thing.

¹¹If there should be in thee a man who is not clean by reason of his issue by night, then he shall go forth out of the camp, and he shall not enter into the camp.

— Deuteronomy 23:12 —

¹³And thou shalt have a place outside of the camp, and thou shalt go out thither,

¹⁴and thou shalt have a trowel on thy girdle; and it shall come to pass when thou wouldest relieve thyself abroad, that thou shalt dig with it, and shalt bring back the earth and cover thy nuisance.
