Joshua 18:12-13

Their border on the north side began at the Jordan, and the border went up to the side of Jericho on the north, and went up through the mountains westward; it ended at the Wilderness of Beth Aven. The border went over from there toward Luz, to the side of Luz (which is Bethel) southward; and the border descended to Ataroth Addar, near the hill that lies on the south side of Lower Beth Horon.
