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 Yhwh separated the tribe of Levi, to bear the ark of the covenant of Yhwh, to stand before Yhwh to minister unto him, and to bless in his name, unto this day. 9Wherefore Levi hath no part nor inheritance with his brethren; Yhwh is his inheritance, according as Yhwh thy God promised him. 10And I stayed in the mount, according to the first time, forty days and forty nights; And Yhwh hearkened unto me at that time also, and Yhwh would not destroy thee.1 11And Yhwh 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
