Joshua 18:17 (KJV)

And the south quarter was from the end of Kirjath–jearim, and the border went out on the west, and went out to the well of waters of Nephtoah:

And the border came down to the end of the mountain that lieth before the valley of the son of Hinnom, and which is in the valley of the giants on the north, and descended to the valley of Hinnom, to the side of Jebusi on the south, and descended to En–rogel,

And was drawn from the north, and went forth to En–shemesh, and went forth toward Geliloth, which is over against the going up of Adummim, and descended to the stone of Bohan the son of Reuben,

And passed along toward the side over against Arabah northward, and went down unto Arabah:

And the border passed along to the side of Beth–hoglah northward: and the outgoings of the border were at the north bay of the salt sea at the south end of Jordan: this was the south coast.
