Deu 24:12-13
And if the man was in distress (עני), the lender was not to lie (sleep) upon his pledge, since the poor man had very often nothing but his upper garment, in which he slept, to give as a pledge. This was to be returned to him in the evening. (A repetition of Exo 22:25-26.) On the expression, “It shall be righteousness unto thee,” see Deu 6:25.
