Genesis 14:2

2they [invaded the Jordan Valley near the Dead Sea, and] made war with Bera king of Sodom, Birsha king of Gomorrah, Shinab king of Admah, Shemeber king of Zeboiim, and the king of Bela 14:2 One of the many facts supporting the antiquity of Genesis is that many of the original names of places mentioned were so old that Moses had to add an explanation in order to identify these ancient names, so that the Israelites returning from Egypt could recognize them. Chapter 14 alone contains six such explanatory notes (Gen 14:2, 3, 7, 8, 15, 17).(that is, Zoar).
