Deuteronomy 23:11-13

Wycliffe Bible

¹¹ before that he be washed in water at the eventide, and after the going down of the sun, he shall turn again into the tents. (until he is washed in water in the evening, and then, after the going down of the sun, he shall return to the camp.)

¹² Thou shalt have a place without the tents, to which thou shalt go out to (do the) needful things of (man)kind;

¹³ and thou shalt bear a little stake in thy girdle; and when thou hast set, thou shalt dig about, and thou shalt cover with earth things voided out, where thou art relieved. (and thou shalt bring a little peg in thy belt; and after that thou hast squatted down, thou shalt dig about, and thou shalt cover with earth the things voided out, where thou art relieved.)
