1 Kings 11:4-8

4For 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 the LORD his God, as was the heart of David his father.

5For Solomon went after Ashtoreth the goddess of the Zidonians, and after Milcom the abomination of the Ammonites.

6And Solomon did that which was evil in the sight of the LORD, and went not fully after the LORD, as did David his father.

7Then did Solomon build an high place for Chemosh the abomination of Moab, in the mount that is before Jerusalem, and for Molech the abomination of the children of Ammon.

8And so did he for all his strange wives, which burnt incense and sacrificed unto their gods.
