23. Took Geshur, and Aram. Geshur was a district to the east and northeast of the Sea of Galilee, later an independent Aramaean kingdom (1 Chron. 3:2; 2 Sam. 3:3; 13:37; 15:8). Aram was the region lying north of Palestine, including Syria and northern Mesopotamia. The people of these districts lying in the regions of Bashan and Mt. Hermon were conquered by Israel but were not expelled, being allowed to “dwell among the Israelites” (Joshua 13:11-13).
Even threescore cities. According to Deut. 3:14 Jair “took all the country of Argob unto the coasts of Geshuri and Maachathi; and called them after his own name, Bashan-havoth-jair” (see Num. 32:40, 41; Joshua 13:30, 31). In the days of Solomon the “towns of Jair” are still referred to, and the number of these cities in Bashan is again given as “threescore great cities with walls and brasen bars” (1 Kings 4:13).
To the sons of Machir. Segub and Jair, with their descendants, were reckoned as sons of Machir, the mother’s father, rather than of Hezron, the father, and thus of Manasseh rather than Judah. The relationship between these two tribes is as follows: Having cast in their lot with Manasseh in the region of Gilead, these descendants of Hezron, who belonged to the tribe of Judah, henceforth had their genealogies reckoned with Manasseh, through the mother. Jair is regularly reckoned as belonging to the tribe of Manasseh (Num. 32:41; Deut. 3:14; Joshua 13:29-13).
