Deuteronomy 23:12-14
Set up a place outside the camp to be used as a toilet area. And make sure that you have a small shovel in your equipment. When you go out to the toilet area, use the shovel to dig a hole. Then, after you relieve yourself, bury the waste in the hole. You must keep your camp clean of filthy and disgusting things. The LORD is always present in your camp, ready to rescue you and give you victory over your enemies. But if he sees something disgusting in your camp, he may turn around and leave.
