The king of the Ammonites answered the messengers of Jephthah, "We're here because Israel took away my land from the Arnon River as far as the Jabbok River and as far as the Jordan River when they came up from Egypt! So restore it as a gesture of good will."

"But the king of Edom wouldn't listen. So they also sent word to the king of Moab, but he wouldn't consent, either. So Israel stayed at Kadesh. Then they went through the desert, circumventing the territory belonging to Edom and Moab. They encamped on the other side of the Arnon River, but never entered the territory of Moab because the Arnon River is the border of Moab.

They took possession of the entire territory of the Amorites from the Arnon River as far as the Jabbok River and from the desert as far as the Jordan River.

When Israel was living in Heshbon and its surrounding villages, in Aroer and its surrounding villages, and in all the cities that line the banks of the Arnon River these past three hundred years, why didn't you retake them during that time?
