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 And the first lot of the sons of Benjamin, by their families, went up, that they should wield the land betwixt the sons of Judah and the sons of Joseph. (And the first lot went out to the sons of Benjamin, by their families, that they should possess the land between the sons of Judah and the sons of Joseph.)

12 And the term of them was against the north from (the) Jordan, and it passed by the side of Jericho at the north coast; and it ascended from thence against the west to the hilly places, and it came to the wilderness of Bethaven; (And their border at the north went out from the Jordan River, and it passed by the northern side of Jericho; and it went up from there to the west to the hill country, and it came to the wilderness of Bethaven;)

13 and it passed beside Luz to the south; that is Bethel; and (then) it goeth down into Atarothaddar, into the hill (country) which is at the south of Lower Bethhoron;

14 and it is bowed, and it compasseth against the sea, at the south of the hill that beholdeth Bethhoron against the north; and the outgoings thereof be into Kiriathbaal, which is called also Kiriathjearim, the city of the sons of Judah; this is the great coast against the sea, at the west. (and then it is turned, and it goeth to the west, southward from the hill country that beholdeth Bethhoron; and its end, or its limit, is Kiriathbaal, which is also called Kiriathjearim, the city of the sons of Judah; this is the western border.)

15 And from the south, by the part of Kiriathjearim, the term goeth out against the sea, and cometh till to the well of (the) waters of Nephtoah; (And in the south, from the edge of Kiriathjearim, the border goeth out toward the west, and cometh unto the well of the waters of Nephtoah;)
