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 the children of Binyamin came up according to their families: and the border of their lot went out between the children of Yehudah and the children of Yosef.
12 Their border on the north quarter was from the Yarden; and the border went up to the side of Yericho on the north, and went up through the hill-country westward; and the goings out of it were at the wilderness of Beit-Aven.
13 The border passed along from there to Luz, to the side of Luz (the same is Beit-El), southward; and the border went down to `Atarot-Addar, by the mountain that lies on the south of Beit-Horon the lower.
14 The border extended [there], and turned about on the west quarter southward, from the mountain that lies before Beit-Horon southward; and the goings out of it were at Kiryat-Ba`al (the same is Kiryat-Ye`arim), a city of the children of Yehudah: this was the west quarter.
15 The south quarter was from the uttermost part of Kiryat-Ye`arim; and the border went out westward, and went out to the spring of the waters of Nefto'ach;
