Then they went along through the wilderness, and compassed the land of Edom, and the land of Moab, and came by the east side of the land of Moab, and pitched on the other side of Arnon, but came not within the border of Moab: for Arnon was the border of Moab.

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

And they possessed all the borders of the Amorites, from Arnon even to Jabbok, and from the wilderness even to Jordan.

While Israel dwelt in Heshbon and her towns, and in Aroer and her towns, and in all the cities that are along by the borders of Arnon, three hundred years? why therefore did ye not recover them within that time?
