8 And we took the land at that time out of the hand of the two kings of the Amorites that were beyond the Jordan, from the valley of the Arnon unto mount Hermon; 9 ([which] Hermon the Sidonians call Sirion, and the Amorites call it Senir;) 10 all the cities of the plain, and all Gilead, and all Bashan, unto Salecah and Edrei, cities of the kingdom of Og in Bashan. 11 (For only Og king of Bashan remained of the remnant of the Rephaim; behold, his bedstead was a bedstead of iron; is it not in Rabbah of the children of Ammon? nine cubits was the length thereof, and four cubits the breadth of it, after the cubit of a man.)
12 And 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 the cities thereof, gave I unto the Reubenites and to the Gadites: 13 and the rest of Gilead, and all Bashan, the kingdom of Og, gave I unto 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, unto the border of the Geshurites and the Maacathites, and called them, even Bashan, after his own name, Havvoth-jair, unto this day.) 15 And I gave Gilead unto Machir. 16 And unto the Reubenites and unto the Gadites I gave from Gilead even unto the valley of the Arnon, the middle of the valley, and the border [thereof], even unto the river Jabbok, which is the border of the children of Ammon; 17 the Arabah also, and the Jordan and the border [thereof], from Chinnereth even unto the sea of the Arabah, the Salt Sea, under the slopes of Pisgah eastward.

Commentary on Deuteronomy 3:1-11
(Read Deuteronomy 3:1-11)
1-11 Og was very powerful, but he did not take warning by the ruin of Sihon, and desire conditions of peace. He trusted his own strength, and so was hardened to his destruction. Those not awakened by the judgments of God on others, ripen for the like judgments on themselves.
Commentary on Deuteronomy 3:12-20
(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.
