12 "When we took possession of this land at that time, I gave to the Reubenites and the Gadites the territory beginning at Aro'er, which is on the edge of the valley of the Arnon, and half the hill country of Gilead with its cities; 13 the rest of Gilead, and all Bashan, the kingdom of Og, that is, all the region of Argob, I gave to the half-tribe of Manas'seh. (The whole of that Bashan is called the land of Reph'aim. 14 Ja'ir the Manas'site took all the region of Argob, that is, Bashan, as far as the border of the Gesh'urites and the Ma-ac'athites, and called the villages after his own name, Hav'voth-ja'ir, as it is to this day.) 15 To Machir I gave Gilead, 16 and to the Reubenites and the Gadites I gave the territory from Gilead as far as the valley of the Arnon, with the middle of the valley as a boundary, as far over as the river Jabbok, the boundary of the Ammonites; 17 the Arabah also, with the Jordan as the boundary, from Chin'nereth as far as the sea of the Arabah, the Salt Sea, under the slopes of Pisgah on the east.

This country was settled on the Reubenites, Gadites, and half the tribe of Manasseh: see Numbers 32. Moses repeats the condition of the grant to which they agreed. When at rest, we should desire to see our brethren at rest too, and should be ready to do what we can towards it; for we are not born for ourselves, but are members one of another.
