Genesis 14:2 - Ellicott's Commentary On The Whole Bible

Bera king of Sodom. — The failure of the attempt to explain the names of these five kings, and of the cities over which they ruled (with one or two exceptions), by the help of the Hebrew language makes it probable that the inhabitants of the Ciccar were either Canaanites who had come from the sea-coast, or men of some Hamite stock who had colonised this region from the east. The latter is the more probable view, as they do not seem to have had much affinity either with the Amorites or with the Jebusites, their neighbours.
