8 And at that time we took the land from the hand of the two kings of the Amorites who were on this side of the Jordan, from the River Arnon to Mount Hermon 9 (the Sidonians call Hermon Sirion, and the Amorites call it Senir), 10 all the cities of the plain, all Gilead, and all Bashan, as far as Salcah and Edrei, cities of the kingdom of Og in Bashan. 11 For only Og king of Bashan remained of the remnant of the giants. Indeed his bedstead was an iron bedstead. (Is it not in Rabbah of the people of Ammon?) Nine cubits is its length and four cubits its width, according to the standard cubit.
12 "And this land, which we possessed at that time, from Aroer, which is by the River Arnon, and half the mountains of Gilead and its cities, I gave to the Reubenites and the Gadites. 13 The rest of Gilead, and all Bashan, the kingdom of Og, I gave to half the tribe of Manasseh. (All the region of Argob, with all Bashan, was called the land of the giants. 14 Jair the son of Manasseh took all the region of Argob, as far as the border of the Geshurites and the Maachathites, and called Bashan after his own name, Havoth Jair, to this day.) 15 Also I gave Gilead to Machir. 16 And to the Reubenites and the Gadites I gave from Gilead as far as the River Arnon, the middle of the river as the border, as far as the River Jabbok, the border of the people of Ammon; 17 the plain also, with the Jordan as the border, from Chinnereth as far as the east side of the Sea of the Arabah (the Salt Sea), below the slopes of Pisgah.

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.
