The king of the children of Ammon answered to the messengers of Jephthah, "Because Israel took away my land, when he came up out of Egypt, from the Arnon even to the Jabbok, and to the Jordan: now therefore restore those [lands] again peaceably."

Then they went through the wilderness, and went around the land of Edom, and the land of Moab, and came by the east side of the land of Moab, and they encamped on the other side of the Arnon; but they didn't come within the border of Moab, for the Arnon was the border of Moab.

They possessed all the border of the Amorites, from the Arnon even to the Jabbok, and from the wilderness even to the Jordan.

While Israel lived in Heshbon and its towns, and in Aroer and its towns, and in all the cities that are along by the side of the Arnon, three hundred years; why didn't you recover them within that time?
