Joshua 13:8-10

8Moses had already given land to the tribes of Reuben, Gad, and the other half of Manasseh. Their land was on the east side of the Jordan River. Moses, the Lord's servant, had given a piece of land to each tribe.

9Their land went from Aroer, on the edge of the Arnon valley and the town in the middle of the valley. It included all the flat land of Medeba, as far as Dibon.

10It included all the towns of Sihon, king of the Amorites, who ruled in Heshbon. It went to the border of the Amorites' land.
