Numbers 21:21-32 New American Bible (Revised Edition) (NABRE)
Victory over Sihon. 21 Now Israel sent messengers to Sihon, king of the Amorites, with the message, 22 “Let us pass through your land. We will not turn aside into any field or vineyard, nor will we drink any well water, but we will go straight along the King’s Highway until we have passed through your territory.” 23 Sihon, however, would not permit Israel to pass through his territory, but mustered all his forces and advanced against Israel into the wilderness. When he reached Jahaz, he engaged Israel in battle. 24 But Israel put him to the sword, and took possession of his land from the Arnon to the Jabbok and as far as Jazer of the Ammonites, for Jazer is the boundary of the Ammonites. 25 Israel seized all the towns here, and Israel settled in all the towns of the Amorites, in Heshbon and all its dependencies. 26 For Heshbon was the city of Sihon, king of the Amorites, who had fought against the former king of Moab and had taken all his land from him as far as the Arnon. 27 That is why the poets say:
“Come to Heshbon, let it be rebuilt,
31 So Israel settled in the land of the Amorites. 32 Moses sent spies to Jazer; and the Israelites captured it with its dependencies and dispossessed the Amorites who were there.
Judges 11:19-22 New American Bible (Revised Edition) (NABRE)
19 Then Israel sent messengers to the Amorite king Sihon, who was king of Heshbon. Israel said to him, “Let me pass through your land to my own place.” 20 But Sihon refused to let Israel pass through his territory. He gathered all his soldiers, and they encamped at Jahaz and fought Israel. 21 But the Lord, the God of Israel, delivered Sihon and his entire army into the power of Israel, who defeated them and occupied all the land of the Amorites who lived in that region. 22 They occupied all of the Amorite territory from the Arnon to the Jabbok and the wilderness to the Jordan.
