12 Thou shalt have a place also outside the camp, and shalt go forth thither. 13 And thou shalt have a shovel amongst thy weapons, and it shall be, when thou sittest down abroad, thou shalt dig therewith, and shalt turn back and cover that which is come from thee. 14 For Jehovah thy God walketh in the midst of thy camp, to deliver thee, and to give up thine enemies before thee; and thy camp shall be holy, that he see nothing unseemly with thee, and turn away from thee.
Matthew Henry's Commentary on Deuteronomy 23:12-14
Commentary on Deuteronomy 23:9-14
(Read Deuteronomy 23:9-14)
The camp of the Lord must have nothing offensive in it. If there must be this care taken to preserve the body clean, much more should we be careful to keep the mind pure.
