Deuteronomy 10:8-9

That’s when GOD set apart the tribe of Levi to carry GOD’s Covenant Chest, to be on duty in the Presence of GOD, to serve him, and to bless in his name, as they continue to do today. And that’s why Levites don’t have a piece of inherited land as their kinsmen do. GOD is their inheritance, as GOD, your God, promised them.
