Joshua 18:15-19
18:15 The southern side started on the edge of Kiriath Jearim and extended westward to the spring of the waters of Nephtoah.
18:16 The border then descended to the edge of the hill country near the Valley of Ben Hinnom located in the Valley of the Rephaites to the north. It descended through the Valley of Hinnom to the slope of the Jebusites to the south and then down to En Rogel.
18:17 It went northward, extending to En Shemesh and Geliloth opposite the Pass of Adummim, and descended to the Stone of Bohan son of Reuben.
18:18 It crossed to the slope in front of the Arabah to the north and descended into the Arabah.
18:19 It then crossed to the slope of Beth Hoglah to the north and ended at the northern tip of the Salt Sea at the mouth of the Jordan River. This was the southern border.
