Jair the Manassite took all the region of Argob, that is, Bashan, as far as the border of the Geshurites and the Maacathites, and called the villages after his own name, Havvoth-jair, as it is to this day.)

Matthew Henry Presbyterian @wholebiblehenry

Having shown how this country which they were now in was conquered, in these verses he shows how it was settled upon the Reubenites, Gadites, and half the tribe of Manasseh, which we had the story of before, Num. 32. Here is the rehearsal. 1.

Commenting on Deuteronomy 3:12-20

John Gill Reformed Baptist @doctorgill

Jair the son of Manasseh took all the country of Argob,.... Or Trachonitis; the small towns belonging to Gilead, as in Num 32:41. unto the coasts of Geshuri and Maachathi; these were little kingdoms in Syria, on which the country of Argob bordered, and had kings over them in the time of David, and came not into the possession of the Israelites; see Jos 13:13.

Jamieson-Fausset-Brown Reformed @jfbcommentary

Jair the son of Manasseh took all the country of Argob--The original inhabitants of the province north of Bashan, comprising sixty cities (Deu 3:4), not having been extirpated along with Og, this people were afterwards brought into subjection by the energy of Jair.
