12 This land we took in possession at that time: from Aroer, which is by the valley of the Arnon, and half the hill country of Gilead, and its cities, gave I to the Reubenites and to the Gadites: 13 and the rest of Gilead, and all Bashan, the kingdom of Og, gave I to the half-tribe of Manasseh; all the region of Argob, even all Bashan. (The same is called the land of Rephaim. 14 Jair the son of Manasseh took all the region of Argob, to the border of the Geshurites and the Maacathites, and called them, even Bashan, after his own name, Havvoth Jair, to this day.) 15 I gave Gilead to Machir. 16 To the Reubenites and to the Gadites I gave from Gilead even to the valley of the Arnon, the middle of the valley, and the border of it, even to the river Jabbok, which is the border of the children of Ammon; 17 the Arabah also, and the Jordan and the border of it, from Chinnereth even to the sea of the Arabah, the Salt Sea, under the slopes of Pisgah eastward.

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.
