1 Kings 11:5-7

Solomon worshiped Ashtoreth, the goddess of the Sidonians, and Molech, the detestable god of the Ammonites. In this way, Solomon did what was evil in the LORD’s sight; he refused to follow the LORD completely, as his father, David, had done. On the Mount of Olives, east of Jerusalem, he even built a pagan shrine for Chemosh, the detestable god of Moab, and another for Molech, the detestable god of the Ammonites.
