Deuteronomy 23:13

And thou shalt have a paddle upon thy weapon; and it shall be, when thou wilt ease thyself abroad, thou shalt dig therewith, and shalt turn back and cover that which cometh from thee:

and you shall have a paddle among your weapons; and it shall be, when you sit down abroad, you shall dig therewith, and shall turn back and cover that which comes from you:

and thou shalt have a paddle among thy weapons; and it shall be, when thou sittest down abroad, thou shalt dig therewith, and shalt turn back and cover that which cometh from thee:

and a nail thou hast on thy staff, and it hath been, in thy sitting without, that thou hast digged with it, and turned back, and covered thy filth;

And you must have a digging tool in your equipment so that when you relieve yourself you can dig a hole and cover up your excrement.
