Deuteronomy 2:24

2:24 Get up, make your way across Wadi Arnon. Look! I have already delivered over to you Sihon the Amorite, king of Heshbon, ¹  and his land. Go ahead! Take it! Engage him in war!

[2:24]  ¹ sn Heshbon is the name of a prominent site (now Tell Hesba„n, about 7.5 mi [12 km] south southwest of Amman, Jordan). Sihon made it his capital after having driven Moab from the area and forced them south to the Arnon (Num 21:26-30). Heshbon is also mentioned in Deut 1:4.
