Deuteronomy 10:5-9

And I turned myself and came down from the mount, and put the tables in the ark which I had made; and there they be, as the LORD commanded me.

And the children of Israel took their journey from Beeroth of the children of Jaakan to Mosera: there Aaron died, and there he was buried; and Eleazar his son ministered in the priest’s office in his stead.

From thence they journeyed unto Gudgodah; and from Gudgodah to Jotbath, a land of rivers of waters.

At that time the LORD separated the tribe of Levi, to bear the ark of the covenant of the LORD, to stand before the LORD to minister unto him, and to bless in his name, unto this day.

Wherefore Levi hath no part nor inheritance with his brethren; the LORD is his inheritance, according as the LORD thy God promised him.
