Deuteronomy 3:12

12 And we wielded in that time the land, from Aroer, which is on the brink of the strand of Arnon, unto the half part of the hill of Gilead; and I gave his cities to Reuben and to Gad. (And so we took the land from Aroer, which is on the bank of the Arnon River, unto half of the hill country of Gilead; and I gave its cities to the tribes of Reuben and of Gad.)

Deuteronomy 3:12 Meaning and Commentary

Deuteronomy 3:12

And this land, which we possessed at that time
Or took possession of, having conquered it; for it still remained in their possession:

from Aroer, which is by the river Arnon:
on the borders of Moab, from thence as far as Gilead was the land which was taken from Sihon king of Heshbon, ( Deuteronomy 2:36 )

and half Mount Gilead, and the cities thereof:
which were taken from Og king of Bashan, ( Deuteronomy 3:10 )

gave I unto the Reubenites, and to the Gadites;

Deuteronomy 3:12 In-Context

10 And we took all the cities that were set in the plain, and all the land of Gilead, and of Bashan, unto Salchah and Edrei, cities of the realm of Og, in Bashan. (And we took all the cities that were set there on the plain, and all the land of Gilead, and of Bashan, unto Salchah and Edrei, cities in the kingdom of Og, in Bashan.)

11 For Og alone, king of Bashan, was left of the generation of giants; and his iron bed is showed, which is in Rabbath, of the sons of Ammon, and it hath nine cubits of length, and four cubits of breadth, at the measure of a cubit of a man's hand. (For only Og, the king of Bashan, was left of the generation of the giants; and his iron bed is on display in the city of Rabbath, of the Ammonites, and it is nine cubits in length, and four cubits in breadth, at the measure of one cubit equal to a man's hand.)

12 And we wielded in that time the land, from Aroer, which is on the brink of the strand of Arnon, unto the half part of the hill of Gilead; and I gave his cities to Reuben and to Gad. (And so we took the land from Aroer, which is on the bank of the Arnon River, unto half of the hill country of Gilead; and I gave its cities to the tribes of Reuben and of Gad.)

13 And I gave the tother part of Gilead, and all Bashan, of the realm of Og, to the half lineage of Manasseh, and all the country of Argob. All Bashan was called the land of giants. (And I gave the other part of Gilead, and all of Bashan, which was Og's kingdom, that is, all the region of Argob, to half of the tribe of Manasseh. Previously, all of Bashan was called the land of the giants.)

14 Jair, the son of Manasseh, wielded all the country of Argob, unto the land of Geshuri and of Maachathi; and he called (the towns there) by his name Bashanhavothjair, that is, the towns of Jair, till into this present day. (Jair, the son of Manasseh, took all the region of Argob, unto the borders of the Geshurites and the Maachathites; and he called the towns there Bashanhavothjair, that is, the towns of Jair, after his own name, and they still be called that unto this present day.)
