Ulangan 1:19

1:19 Then we left Horeb and passed through all that immense, forbidding wilderness that you saw on the way to the Amorite hill country as the Lord our God had commanded us to do, finally arriving at Kadesh Barnea.

Ulangan 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.
