Joshua 18:12-13

12On the north side their boundary began at the Jordan. Then the boundary goes up to the shoulder north of Jericho, then up through the hill country westward, and it ends at the wilderness of Beth-aven.

13From there the boundary passes along southward in the direction of Luz, to the shoulder of Luz (that is, Bethel), then the boundary goes down to Ataroth-addar, on the mountain that lies south of Lower Beth-horon.
