Deuteronomy 12
18 Ref But they will be your food before the Lord your God in the place of his selection, where you may make a feast of them, with your son and your daughter, and your man-servant and your woman-servant, and the Levite who is living with you: and you will have joy before the Lord your God in everything to which you put your hand.
19 Ref See that you do not give up caring for the Levite as long as you are living in your land.
