Joshua 15:3-7

Then it proceeded southward to the ascent of Akrabbim and continued to Zin, then went up by the south of Kadesh-barnea and continued to Hezron, and went up to Addar and turned to Karka.

It continued to Azmon and proceeded to the brook of Egypt, and the border ended at the sea. This shall be your southern border.

The eastern border was the Salt Sea, as far as the mouth of the Jordan. And the border of the north side was from the bay of the sea at the mouth of the Jordan.

Then the border went up to Beth-hoglah, and continued on the north of Beth-arabah, and the border went up to the stone of Bohan the son of Reuben.

And the border went up to Debir from the Valley of Achor, and turned northward toward Gilgal which is opposite the ascent of Adummim, which is on the south of the valley; and the border continued to the waters of En-shemesh and it ended at En-rogel.
