Joshua 18:15-19

15The south border went from the edge of Kiriath-Jearim to the springs of water at Nephtoah.

16Then it went to the edge of the hill country, near Ben Hinnom valley. This was north of the Valley of the Rephaites. It continued down the Hinnom valley, south of the Jebusite city and then went on to En Rogel.

17Then it went north to En Shemesh. It continued to Geliloth, opposite the valley of Adummim. Then it went to the great stone of Bohan, Reuben's son.

18It continued to the north of Beth Arabah down into the Jordan Valley.

19Then it went north of Ben Hoglah, to the north end of the Salt Sea, where the Jordan River ends. That was the south border of Benjamin's land.
