1 Kings 11:4-10

4For when Solomon was old his wives turned away his heart after other gods, and his heart was not wholly true to the LORD his God, as was the heart of David his father. 5For Solomon went after Ashtoreth the goddess of the Sidonians, and after Milcom the abomination of the Ammonites. 6So Solomon did what was evil in the sight of the LORD and did not wholly follow the LORD, as David his father had done. 7Then Solomon built a high place for Chemosh the abomination of Moab, and for Molech the abomination of the Ammonites, on the mountain east of Jerusalem. 8And so he did for all his foreign wives, who made offerings and sacrificed to their gods. 9And the LORD was angry with Solomon, because his heart had turned away from the LORD, the God of Israel, who had appeared to him twice 10and had commanded him concerning this thing, that he should not go after other gods. But he did not keep what the LORD commanded.
