Deuteronomy 24:17-22

Do not be unfair to a foreigner or an orphan. Don’t take a widow’s coat to make sure she pays you back. Remember that you were slaves in Egypt, and the LORD your God saved you from there. That is why I am commanding you to do this. When you are gathering your harvest in the field and leave behind a bundle of grain, don’t go back and get it. Leave it there for foreigners, orphans, and widows so that the LORD your God can bless everything you do. When you beat your olive trees to knock the olives off, don’t beat the trees a second time. Leave what is left for foreigners, orphans, and widows. When you harvest the grapes in your vineyard, don’t pick the vines a second time. Leave what is left for foreigners, orphans, and widows. Remember that you were slaves in Egypt; that is why I am commanding you to do this.
