All these joined forces at the valley of Siddim (that [is], the sea of the salt).

Then the king of Sodom, the king of Gomorrah, the king of Admah, the king of Zeboiim, and the king of Bela (that [is], Zoar) went out, and {they took up battle position} in the Valley of Siddim

Now the Valley of Siddim {was full of tar pits}. And the kings of Sodom and Gomorrah fled and {fell into them}, but the rest fled to the mountains.
