1 Kings 11:3-8

31He had seven hundred wives, princesses, and three hundred concubines, and his wives turned his heart away. 4For when Solomon was old, his wives turned his heart away after other gods; and 2his heart was not 3wholly devoted to the Lord his God, as the heart of David his father had been. 5For Solomon went after 4Ashtoreth the goddess of the Sidonians and after 56Milcom the detestable idol of the Ammonites. 6Solomon did what was evil in the sight of the Lord, and did not follow the Lord fully, as David his father had done. 7Then Solomon built a high place for 7Chemosh the detestable idol of Moab, on the mountain which is 8east of Jerusalem, and for 9Molech the detestable idol of the sons of Ammon. 8Thus also he did for all his foreign wives, who burned incense and sacrificed to their gods.
