Dead Sea: Sea of the Plain

The Jordan River in the Arabah bordered it from Chinnereth to the Sea of the Arabah (the Salt Sea) with the slopes of Pisgah to the east.

…including all the Arabah on the east side of the Jordan and as far as the Sea of the Arabah, below the slopes of Pisgah.

…the flowing water stood still. It backed up as far upstream as Adam, a city in the area of Zarethan, while the water flowing toward the Sea of the Arabah (the Salt Sea) was completely cut off. So the people crossed over opposite Jericho.
