8 "So we took the land of the two Amorite kings east of the Jordan River-all the way from the Arnon Gorge to Mount Hermon. 9 (Mount Hermon is called Sirion by the Sidonians, and the Amorites call it Senir.) 10 We had now conquered all the cities on the plateau and all Gilead and Bashan, as far as the towns of Salecah and Edrei, which were part of Og's kingdom in Bashan. 11 (King Og of Bashan was the last survivor of the giant Rephaites. His bed was made of iron and was more than thirteen feet long and six feet wide. It can still be seen in the Ammonite city of Rabbah.)
12 "When we took possession of this land, I gave to the tribes of Reuben and Gad the territory beyond Aroer along the Arnon Gorge, plus half of the hill country of Gilead with its towns. 13 Then I gave the rest of Gilead and all of Bashan-Og's former kingdom-to the half-tribe of Manasseh. (This entire Argob region of Bashan used to be known as the land of the Rephaites. 14 Jair, a leader from the tribe of Manasseh, conquered the whole Argob region in Bashan, all the way to the border of the Geshurites and Maacathites. Jair renamed this region after himself, calling it the Towns of Jair, as it is still known today.) 15 I gave Gilead to the clan of Makir. 16 But I also gave part of Gilead to the tribes of Reuben and Gad. The area I gave them extended from the middle of the Arnon Gorge in the south to the Jabbok River on the Ammonite frontier. 17 They also received the Jordan Valley, all the way from the Sea of Galilee down to the Dead Sea, with the Jordan River serving as the western boundary. To the east were 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.
