The twelfth region was in the desert along the Dead Sea, and it had the following six towns with their surrounding villages: Beth-Arabah, Middin, Secacah, Nibshan, Salt Town, and En-Gedi.
At Enrogel the border curved north and went to Enshemesh and on east to Geliloth, which is across the valley from Adummim Pass. Then it went down to the Monument of Bohan, who belonged to the Reuben tribe.
Inside the valley it went south as far as the northern hillside of Beth-Hoglah. The last section of the border went from there to the northern end of the Dead Sea, at the mouth of the River Jordan.
