Deuteronomy 23:13

¹¹If there should be in thee a man who is not clean by reason of his issue by night, then he shall go forth out of the camp, and he shall not enter into the camp.

¹²And it shall come to pass toward evening he shall wash his body with water, and when the sun has gone down, he shall go into the camp.

— Deuteronomy 23:13 —

¹⁴and thou shalt have a trowel on thy girdle; and it shall come to pass when thou wouldest relieve thyself abroad, that thou shalt dig with it, and shalt bring back the earth and cover thy nuisance.

¹⁵Because the Lord thy God walks in thy camp to deliver thee, and to give up thine enemy before thy face; and thy camp shall be holy, and there shall not appear in thee a disgraceful thing, and so he shall turn away from thee.
