12 'And this land we have possessed, at that time; from Aroer, which 'is' by the brook Arnon, and the half of mount Gilead, and its cities, I have given to the Reubenite, and to the Gadite; 13 and the rest of Gilead and all Bashan, the kingdom of Og, I have given to the half tribe of Manasseh; all the region of Argob, to all that Bashan, called the land of Rephaim. 14 'Jair son of Manasseh hath taken all the region of Argob, unto the border of Geshuri, and Maachathi, and calleth them by his own name, Bashan-Havoth-Jair, unto this day. 15 And to Machir I have given Gilead. 16 'And to the Reubenite and to the Gadite I have given from Gilead even unto the brook Arnon, the middle of the valley and the border, even unto Jabbok the brook, the border of the sons of Ammon, 17 and the plain, and the Jordan, and the border, from Chinnereth even unto the sea of the plain, the salt sea, under the springs of Pisgah, at the 'sun'-rising.
Matthew Henry's Commentary on Deuteronomy 3:12-17
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.
