Deuteronomy 24
11 Thou shalt stand without, and the man to whom thou dost lend shall bring forth the pledge without unto thee.
12 Ref And if he be a poor man, thou shalt not sleep with his pledge;
13 Ref thou shalt surely restore to him the pledge when the sun goeth down, that he may sleep in his garment, and bless thee: and it shall be righteousness unto thee before Jehovah thy God.
