And the king of the children of Ammon answered unto the messengers of Jephthah, "Because Israel took away my land, when they came out of Egypt, even from Arnon unto Jabbok and from thence unto Jordan, now therefore restore those lands again with fair means."

And then they went along through the wilderness, and compassed the land of Edom, and the land of Moab, and came along by the east side of the land of Moab, and pitched on the other side of the river of Arnon, and came not within the coasts of the Moabites: for Arnon was their utmost border.

And they conquered all the coasts of the Amorites, from Arnon unto Jabbok, and from the wilderness unto Jordan.

all the while Israel dwelt in Heshbon and her towns, and in Aroer and her towns, and in all the cities that be along by the coasts of Arnon, three hundredth years? Why didst thou not recover them in all that space?
