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.

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.
