Elah is mentioned 4 times in scripture, across 1 book of the Old Testament. First named in scripture around 930 BC.
The son and successor of Baasha, king of Israel (1 Kings 16:8-10). He was killed while drunk by Zimri, one of the captains of his chariots, and was the last king of the line of Baasha. Thus was fullfilled the prophecy of Jehu (6, 7, 11-14).
