1 Kings 11:4-8 - Solomon's Apostasy
4 For it happened, when Solomon was old, that his wives turned away his heart after other gods; and his heart was not perfect with the LORD his God, as was the heart of David his father. 5 For Solomon went after Ashtoreth the goddess of the Sidonians, and after Milcom the abomination of the Ammonites. 6 Solomon did that which was evil in the sight of the LORD, and did not completely follow after the LORD, as did David his father.
7 Then Solomon built a high place for Chemosh the abomination of Moab, on the mountain that is before Jerusalem, and for Molech the abomination of the children of Ammon. 8 So he did for all his foreign wives, who burnt incense and sacrificed to their gods.
