"You shall say before the LORD your God, 'I have removed the sacred portion from my house, and also have given it to the Levite and the alien, the orphan and the widow, according to all Your commandments which You have commanded me; I have not transgressed or forgotten any of Your commandments." (Deuteronomy 26:13)
"The Levitical priests, the whole tribe of Levi, shall have no portion or inheritance with Israel; they shall eat the LORD'S offerings by fire and His portion." (Deuteronomy 18:1) This commandment is literally that the members of the tribe of Levi have no portion or inheritance in the Land of Israel.
