Deuteronomy 23:10-15 New American Bible (Revised Edition) (NABRE)
Cleanliness in Camp. 10 When in camp during an expedition against your enemies, you shall keep yourselves from anything bad. 11 If one of you becomes unclean because of a nocturnal emission, he shall go outside the camp; he shall not come back into the camp. 12 Toward evening, he shall bathe in water; then, when the sun has set, he may come back into the camp. 13 Outside the camp you shall have a place set aside where you shall go. 14 You shall keep a trowel in your equipment and, when you go outside to relieve yourself, you shall dig a hole with it and then cover up your excrement. 15 Since the Lord, your God, journeys along in the midst of your camp to deliver you and to give your enemies over to you, your camp must be holy, so that he does not see anything indecent in your midst and turn away from you.
