"With Baal, a king of Sidon (B.C. 940-908), father of Jezebel," who was the wife of Ahab (1 Kings 16:31). He is said to have "been also a priest of Astarte, whose worship was closely allied" "to that of Baal, and this may account for his daughter's zeal in" promoting idolatry in Israel. This marriage of Ahab was most "fatal to both Israel and Judah. Dido, the founder of Carthage," was his granddaughter.
