Deuteronomy 23:12-14

Mark out an area outside the camp where you can go to relieve yourselves. Along with your weapons have a stick with you. After you relieve yourself, dig a hole with the stick and cover your excrement. GOD, your God, strolls through your camp; he’s present to deliver you and give you victory over your enemies. Keep your camp holy; don’t permit anything indecent or offensive in GOD’s eyes. * * *
