Deuteronomy 10:6-11

6And 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. 7From thence they journeyed unto Gudgodah; and from Gudgodah to Jotbath, a land of rivers of waters.

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 unto him, and to bless in his name, unto this day. 9Wherefore Levi hath no part nor inheritance with his brethren; the Lord is his inheritance, according as the Lord thy God promised him. 10And I stayed in the mount, according to the first time, forty days and forty nights; and the Lord hearkened unto me at that time also, and the Lord would not destroy thee.1 11And the Lord said unto me, Arise, take thy journey before the people, that they may go in and possess the land, which I sware unto their fathers to give unto them.2
