Joshua 18:12-13

12And their border on the north side was from the Jordan; and the border went up to the side of Jericho on the north, and went up to the mountain westward; and ended at the wilderness of Beth-Aven;

13and the border passed on from thence toward Luz, to the south side of Luz, which is Bethel: and the border went down to Ataroth-Addar, near the hill that is on the south of the lower Beth-horon.
