Joshua 18:15-19

And the south part is from the farthest point of Kiriath-jearim, and the line goes out to the west to the fountain of the waters of Nephtoah: And the line goes down to the farthest part of the mountain facing the valley of the son of Hinnom, which is on the north of the valley of Rephaim: from there it goes down to the valley of Hinnom, to the side of the Jebusite on the south as far as En-rogel; And it goes to En-shemesh and on to Geliloth, opposite the way up to Adummim, and it goes down to the stone of Bohan, the son of Reuben; And it goes on to the side facing the Arabah to the north, and down to the Arabah; And on to the north side of Beth-hoglah, ending at the north inlet of the Salt Sea at the south end of Jordan; this is their limit on the south.
