Barnes' Notes
In these apparently unimportant words is contained the record of the Israelite Numbers 32:39 occupation of Gilead north of the Jabbok; a territory which, though populated, like southern Gilead, by the Amorites (Deuteronomy 3:9; Joshua 2:10, etc.), formed part of the domain of Og king of Bashan, who was himself of a different race Deuteronomy 3:2; Joshua 12:5; Joshua 13:11. We are not told whether they were led there by express warrant of God, or whether their advance upon Bashan was provoked by Og and his people.
At Edrei - Now Edhra' ah, commonly Der' a; situate on a branch of the Jarmuk. This river formed the boundary between Gilead and Bashan.
