Judges 11:22

And they possessed all the coasts of the Amorites
Peaceably and quietly, nor did any pretend to call their right in question, or dispute their title, or give them any disturbance:

from Arnon unto Jabbok:
which was the length of the country, and the direction was from south to north, and reached from the river Arnon, the border of Moab, to the river Jabbok, the border of Ammon; so that it included no part of what was at this time in the possession of either:

and from the wilderness even unto Jordan;
which was the breadth of it, and its direction was from the west to the east, reaching from the wilderness of Arabia to the river Jordan.
