Numbers 34:12

and the border, skirting the lake on the eastern side, shall go down to Jordan, and the goings out of it shall be At the Salt Sea, the Dead Sea, both the Sea of Galilee and the Jordan thus being included within the boundary of Canaan proper. This shall be your land with the coasts thereof round about. "This land of Canaan was still now to be distributed by lot, as the land of the inheritance in the narrower and stricter sense. Still, the inheritance of Reuben, Gad, and the half tribe of Manasseh, the east Jordan region, was included. For here it treats specially of that part of the inheritance which was yet to be conquered and distributed. " (Lange.)
