Deuteronomy 23:9-14 - Cleanliness Of The Camp

⁹ When you go out to war and put your tents in position, keep from every evil thing. ¹⁰ If any man among you becomes unclean through anything which has taken place in the night, he is to go out from the tent-circle and keep outside it: ¹¹ But when evening comes near, let him take a bath: and after sundown he may come back to the tents. ¹² Let there be a place outside the tent-circle to which you may go; ¹³ And have among your arms a spade; and when you have been to that place, let that which comes from you be covered up with earth: ¹⁴ For the Lord your God is walking among your tents, to keep you safe and to give up into your hands those who are fighting against you; then let your tents be holy, so that he may see no unclean thing among you, and be turned away from you
