Moses had given no land to the tribe of Levi. As the Lord had told Moses, they were to receive as their possession a share of the sacrifices burned on the altar to the Lord God of Israel.
Their territory extended to Aroer (on the edge of the Arnon Valley) and the city in the middle of that valley and included all the plateau around Medeba.
Now, as he promised, the Lord your God has given the other Israelites peace. So go back home to the land which you claimed for your own, the land on the east side of the Jordan, that Moses, the Lord's servant, gave you.
