So the Lord our God delivered into our hands Og also the king of Bashan, and all his people,.... As well as Sihon king of Heshbon:
and we smote him, till none was left to him remaining; or left alive, all were slain with the sword; See Gill on Numbers 21:35.
Argob was the capital of a district in Bashan of the same name, which, together with other fifty-nine cities in the same province, were conspicuous for their lofty and fortified walls. It was a war of extermination. Houses and cities were razed to the ground; all classes of people were put to the sword; and nothing was saved but the cattle, of which an immense amount fell as spoil into the hands of the conquerors. Thus, the two Amorite kings and the entire population of their dominions were extirpated. The whole country east of the Jordan--first upland downs from the torrent of the Arnon on the south to that of the Jabbok on the north; next the high mountain tract of Gilead and Bashan from the deep ravine of Jabbok--became the possession of the Israelites.
