Deuteronomy 24:11-20

Stand outside while the man you are making the loan to brings the security out to you. If he is a poor man, do not sleep with the garment he has given as security. Be sure to return it  to him at sunset. Then he will sleep in it and bless you, and this will be counted as righteousness to you before the Lord your God.  “Do not oppress a hired worker who is poor and needy, whether one of your Israelite brothers or one of the resident aliens in a town  in your land. You are to pay him his wages each day before the sun sets, because he is poor and depends on them.  Otherwise he will cry out to the Lord against you, and you will be held guilty. “Fathers are not to be put to death for their children, and children are not to be put to death for their fathers; each person will be put to death for his own sin.  Do not deny justice to a resident alien or fatherless child, and do not take a widow’s garment as security. Remember that you were a slave in Egypt, and the Lord your God redeemed  you from there. Therefore I am commanding you to do this.  “When you reap the harvest in your field, and you forget a sheaf in the field, do not go back to get it. It is to be left for the resident alien, the fatherless, and the widow, so that the Lord your God may bless you in all the work of your hands.  When you knock down the fruit from your olive tree, do not go over the branches again. What remains will be for the resident alien, the fatherless, and the widow.
