Joshua 18:12-13

12And their border on the north side was from Jordan; and the border went up to the side of Jericho on the north side, and went up through the mountains westward; and the goings out thereof were at the wilderness of Beth–aven.

13And the border went over from thence toward Luz, to the side of Luz, which is Beth–el, southward; and the border descended to Ataroth–adar, near the hill that lieth on the south side of the nether Beth–horon.
