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 Yhwh his God, as was the heart of David his father.

5For Solomon went after Ashtoreth the goddess of the Sidonians, and after Milcom the abomination of the Ammonites.1

6And Solomon did evil in the sight of Yhwh, and went not fully after Yhwh, as did David his father.2

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

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