1 Kings 11:4, 33

In Solomon’s old age, they turned his heart to worship other gods instead of being completely faithful to the LORD his God, as his father, David, had been.

For Solomon has abandoned me and worshiped Ashtoreth, the goddess of the Sidonians; Chemosh, the god of Moab; and Molech, the god of the Ammonites. He has not followed my ways and done what is pleasing in my sight. He has not obeyed my decrees and regulations as David his father did.
