Joshua 18:14

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 city belonging to the people of Judah . This forms the western side .

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.

And the border was drawn thence , and compassed the corner of the sea southward, from the hill that lieth before Beth–horon southward; and the goings out thereof were at Kirjath–baal, which is Kirjath–jearim, a city of the children of Judah : this was the west quarter.
