Deuteronomy 10:6-9

6(Now the children of Israel journeyed from the wells of Bene Jaakan to Moserah, where Aaron died, and where he was buried; and Eleazar his son ministered as priest in his stead.

7From there they journeyed to Gudgodah, and from Gudgodah to Jotbathah, a land of rivers of water.

8At 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 to Him and to bless in His name, to this day.

9Therefore Levi has no portion nor inheritance with his brethren; the Lord is his inheritance, just as the Lord your God promised him.)
