1 Kings 11:4, 33

For it came to pass, when Solomon was old, that his wives turned away his heart after other gods; and his heart was not perfect with Jehovah his God, as was the heart of David his father.

because that they have forsaken me, and have worshipped Ashtoreth the goddess of the Sidonians, Chemosh the god of Moab, and Milcom the god of the children of Ammon; and they have not walked in my ways, to do that which is right in mine eyes, and to keep my statutes and mine ordinances, as did David his father.
