Joshua 18:13 Meaning and Commentary

Joshua 18:13

And the border went over from thence towards Luz
From Bethaven, where the northern border ended, the western began, and went on to Luz:

to the side of Luz, which is Bethel, southward;
that is, passed along, leaving that city to the south, which formerly was called Luz, but now Bethel, which though distinct places formerly, yet being very near, might in process of time be joined; (See Gill on Joshua 16:2);

and the border descended to Atarothadar,
the same with Archiataroth, (See Gill on Joshua 16:2), and (See Gill on Joshua 16:5):

near the hill that [lieth] on the south side of the nether Bethhoron;
so called to distinguish it from Bethhoron the upper, situated on an hill or mountain, ( Joshua 16:5 ) ; this was rebuilt by Solomon, ( 1 Kings 9:17 ) .

Joshua 18:13 In-Context

11 The lot of the tribe of Benjamin according to its families came up, and the territory allotted to it fell between the tribe of Judah and the tribe of Joseph.
12 On the north side their boundary began at the Jordan; then the boundary goes up to the slope of Jericho on the north, then up through the hill country westward; and it ends at the wilderness of Beth-aven.
13 From there the boundary passes along southward in the direction of Luz, to the slope of Luz (that is, Bethel), then the boundary goes down to Ataroth-addar, on the mountain that lies south of Lower Beth-horon.
14 Then the boundary goes in another direction, turning on the western side southward from the mountain that lies to the south, opposite Beth-horon, and it ends at Kiriath-baal (that is, Kiriath-jearim), a town belonging to the tribe of Judah. This forms the western side.
15 The southern side begins at the outskirts of Kiriath-jearim; and the boundary goes from there to Ephron, to the spring of the Waters of Nephtoah;
