Joshua 18:15-19

15— And the south side was from the extreme end of Kirjath-jearim, and the border went out on the west, and went out to the spring of the waters of Nephtoah.

16And the border went down to the end of the mountain that is before the valley of the son of Hinnom, which is in the valley of Rephaim on the north, and went down the valley of Hinnom, to the side of the Jebusite on the south, and went down to En-rogel;

17and it reached along on the north, and went forth to En-shemesh, and went forth towards Geliloth, which is opposite to the ascent of Adummim, and went down to the stone of Bohan, the son of Reuben,

18and passed along towards the side opposite to Arabah northwards, and went down to Arabah;

19and the border passed on to the side of Beth-hoglah on the north, and the border ended at the tongue of the salt sea northward, at the south end of the Jordan: this is the southern border.
