12 Of the land that we possessed at that time, I gave the Reubenites and the Gadites the territory north of Aroer along the Brook Arnon and half the hill country of Gilead with its towns. 13 I gave the half-tribe of Manasseh the rest of Gilead and all of Bashan, Og's kingdom - all the region of Argob, which takes in all of Bashan. This used to be known as the Land of the Rephaites. 14 Jair, a son of Manasseh, got the region of Argob to the borders of the Geshurites and Maacathites. He named the Bashan villages after himself, Havvoth Jair (Jair's Tent-Villages). They're still called that. 15 I gave Gilead to Makir. 16 I gave the Reubenites and Gadites the land from Gilead down to the Brook Arnon, whose middle was the boundary, and as far as the Jabbok River, the boundary line of the People of Ammon. 17 The western boundary was the Jordan River in the Arabah all the way from the Kinnereth (the Sea of Galilee) to the Sea of the Arabah (the Salt Sea or Dead Sea) at the base of the slopes of Mount Pisgah on the east.

(Read Deuteronomy 3:12-20)
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.
