14:2 went to war4 against Bera king of Sodom, Birsha king of Gomorrah, Shinab king of Admah, Shemeber king of Zeboiim, and the king of Bela (that is, Zoar).5
snWent to war. The conflict here reflects international warfare in the Early and Middle Bronze periods. The countries operated with overlords and vassals. Kings ruled over city states, or sometimes a number of city states (i.e., nations). Due to their treaties, when one went to war, those confederate with him joined him in battle. It appears here that it is Kedorlaomer’s war, because the western city states have rebelled against him (meaning they did not send products as tribute to keep him from invading them).
