And eastward he inhabited
Either Bela, or the tribe of Reuben:
unto the entering in of the wilderness;
the wilderness of Kedemoth, which was near to Sihon king of Heshbon, whose land the Reubenites inhabited, ( Deuteronomy 2:26 )
from the river Euphrates;
a learned man F18 thinks that this river Phrat was different from the Euphrates near Babylon, which was northward, since this was to the east or southeast:
because their cattle were multiplied in the land of Gilead;
therefore their habitation was extended further, even to the river Euphrates, as in the days of David and Solomon, ( 2 Samuel 8:3 ) ( 1 Kings 4:21 ) .
