Joshua 12:2-3

2King Sihon of the Amorites, who lived in Heshbon, was defeated. His kingdom included Aroer, on the edge of the Arnon Gorge, and extended from the middle of the Arnon Gorge to the Jabbok River, which serves as a border for the Ammonites. This territory included the southern half of the territory of Gilead.

3Sihon also controlled the Jordan Valley and regions to the east—from as far north as the Sea of Galilee to as far south as the Dead Sea, including the road to Beth-jeshimoth and southward to the slopes of Pisgah.
