Numbers 21:21-25

ISV(i) 21 Israel Conquers the AmoritesLater, Israel sent messengers to Sihon, king of the Amorites, who conveyed this request: 22 “Permit us to pass through your land. We won’t trespass in your fields or vineyards. We won’t drink water from any well, and we’ll only travel along the King’s Highway until we’ve passed through your territory.”
23 Instead of letting Israel pass through his territory, Sihon mustered his entire army and marched out to meet them in the wilderness. He arrived at Jahaz and attacked Israel. 24 But Israel defeated him in battle and took possession of all his lands from Arnon to Jabbok, including the Ammonites, even though the border of the Ammonites was strong. 25 So Israel captured all of those cities, occupied all the Amorite cities in Heshbon, and all its towns.
