Deuteronomy 24:10-13

10When thou dost lend thy brother any thing, thou shalt not go into his house to take his pledge.1 11Thou shalt stand outside, and the man to whom thou dost lend shall bring out the pledge outside to thee. 12And if the man is poor, thou shalt not sleep with his pledge: 13In any case thou shalt deliver to him the pledge again when the sun goeth down, that he may sleep in his own raiment, and bless thee: and it shall be righteousness to thee before the LORD thy God.
