All of these came as allies to the Valley of Siddim (that is, the Dead Sea).

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 lined up for battle in the Valley of Siddim

Now the Valley of Siddim contained many asphalt pits, and as the kings of Sodom and Gomorrah fled, some fell into them, but the rest fled to the mountains.
