Jamieson, Fausset and Brown on 1 Kings 16:29-33

29-33. Ahab the son of Omri did evil in the sight of the Lord above all that were before him--The worship of God by symbols had hitherto been the offensive form of apostasy in Israel, but now gross idolatry is openly patronized by the court. This was done through the influence of Jezebel, Ahab's queen. She was "the daughter of Eth-baal, king of the Zidonians." He was priest of Ashtaroth or Astarte, who, having murdered Philetes, king of Tyre, ascended the throne of that kingdom, being the eighth king since Hiram. Jezebel was the wicked daughter of this regicide and idol priest--and, on her marriage with Ahab, never rested till she had got all the forms of her native Tyrian worship introduced into her adopted country.
