1 Kings 11:7-10

7At that time on a hill east of Jerusalem, Solomon built a high place for Chemosh the abomination of Moab and for Molech the abomination of the Ammonites. 8He did the same for all his foreign wives, who burned incense and sacrificed to their gods.

9Now the LORD grew angry with Solomon, because his heart had turned away from the LORD, the God of Israel, who had appeared to him twice. 10Although He had warned Solomon explicitly not to follow other gods, Solomon did not keep the LORD’s command.
