And the border went over from thence toward Luz, to the side of Luz, which is Bethel, southward; and the border descended to Atarothadar, near the hill that lieth on the south side of the nether Bethhoron.
From 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.
From there the border went toward Luz, to the southern slope of Luz (that is, Bethel); it then went down by Ataroth-addar, over the hill south of Lower Beth-horon.
Joshua 18:13 In-Context
The first lot came up for the tribe of Benjamin according to its clans. Their allotted territory lay between the tribes of Judah and Joseph:
On the north side their boundary began at the Jordan, passed the northern slope of Jericho and headed west into the hill country, coming out at the wilderness of Beth Aven.
From there it crossed to the south slope of Luz (that is, Bethel) and went down to Ataroth Addar on the hill south of Lower Beth Horon.
From the hill facing Beth Horon on the south the boundary turned south along the western side and came out at Kiriath Baal (that is, Kiriath Jearim), a town of the people of Judah. This was the western side.
The southern side began at the outskirts of Kiriath Jearim on the west, and the boundary came out at the spring of the waters of Nephtoah.
