Deuteronomy 24:11-13

ASV(i) 11 Thou shalt stand without, and the man to whom thou dost lend shall bring forth the pledge without unto thee. 12 And if he be a poor man, thou shalt not sleep with his pledge; 13 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.
