Cf. Numbers 32:40; 1 Chronicles 2:22.)
The possession of the tribes of Reuben and Gad is here more exactly defined. Its southern boundary was the middle of the valley (the wady) of the Arnon; half the valley, and the border, i.e. the middle of the ravine (or wady) and its edge; a more precise definition of the river Arnon; the brook which flowed through the middle of the ravine was to be their boundary line to the south. On the northeast the Upper Jabbok (Nahr Amman) was to be their boundary; this separated them from Ammonitis, the region of the children of Ammon (Numbers 21:24). On the west the 'Arabah (Ghor), and the Jordan and its border (its east bank), from Chinnereth (Kinnereth), a fenced city by the sea of Galilee, thence called "the sea of Chinnereth" (Numbers 34:11; Joshua 12:3; Joshua 19:35), to the sea of the 'Arabah, the salt sea, under Ashdoth-pisgah—the slopes (literally, the outpourings, the place where the mountain torrents flow out, hence the base of the hill) of Pisgah (Numbers 21:15; Numbers 27:12)—eastward; i.e. simply the east side of the 'Arabah and the Jordan.
