Deuteronomy 1:4

It was after he had slain Sihon the king of the Amorites, who lived in Heshbon, and Og the king of Bashan, who lived at Ashtaroth in Edrei.
Deuteronomy 1:4 Modern English Version (MEV)
 
****************
 
After he had slain Sihon the king of the Amorites, which dwelt in Heshbon,.... Either Moses, speaking of himself in the third person, or rather the Lord, to whom Moses ascribes the victory; of this king, and his palace, and the slaughter of him, see Num_21:24,
 
and Og the king of Bashan, which dwelt at Ashtaroth in Edrei; or near Edrei; for Edrei was not the name of a country, in which Ashtaroth was, but of a city at some distance from it, about six miles, as Jerom says (g); hither Og came from Ashtaroth his palace to fight with Israel, and where he was slain, see Num_21:33. Ashtaroth was an ancient city formerly called Ashtaroth Karnaim, and was the seat of the Rephaim, or giants, from whom Og sprung; see Gill on Gen_14:5, see also Deu_3:11. Jerom says (h) in his time there were two castles in Batanea (or Bashan) called by this name, nine miles distant from one another, between Adara (the same with Edrei) and Abila; and in another place he says (i) Carnaim Ashtaroth is now a large village in a corner of Batanea, and is called Carnea, beyond the plains of Jordan; and it is a tradition that there was the house of Job.
