8 So at that time we took from the two kings of the Amorites the land beyond the Jordan, from the Wadi Arnon to Mount Hermon 9 (the Sidonians call Hermon Sirion, while the Amorites call it Senir), 10 all the towns of the tableland, the whole of Gilead, and all of Bashan, as far as Salecah and Edrei, towns of Og's kingdom in Bashan. 11 (Now only King Og of Bashan was left of the remnant of the Rephaim. In fact his bed, an iron bed, can still be seen in Rabbah of the Ammonites. By the common cubit it is nine cubits long and four cubits wide.)
12 As for the land that we took possession of at that time, I gave to the Reubenites and Gadites the territory north of Aroer, that is on the edge of the Wadi Arnon, as well as half the hill country of Gilead with its towns, 13 and I gave to the half-tribe of Manasseh the rest of Gilead and all of Bashan, Og's kingdom. (The whole region of Argob: all that portion of Bashan used to be called a land of Rephaim; 14 Jair the Manassite acquired the whole region of Argob as far as the border of the Geshurites and the Maacathites, and he named them-that is, Bashan-after himself, Havvoth-jair, 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 Wadi Arnon, with the middle of the wadi as a boundary, and up to the Jabbok, the wadi being boundary of the Ammonites; 17 the Arabah also, with the Jordan and its banks, from Chinnereth down to the sea of the Arabah, the Dead Sea, with the lower slopes of Pisgah on the east.

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.
