1 Kings 11:4-8 - Solomon's Apostasy

⁴ For when Solomon was old, his wives turned his heart away after other gods; and his heart was not completely devoted to the Lord his God, as was the heart of his father David. ⁵ For Solomon went after Ashtoreth, the [fertility] goddess of the Sidonians, and after Milcom the horror (detestable idol) of the Ammonites. ⁶ Solomon did evil [things] in the sight of the Lord, and did not follow the Lord fully, as his father David had done.

⁷ Then Solomon built a high place for [worshiping] Chemosh the horror (detestable idol) of Moab, on the hill which is east of Jerusalem, and for Molech the horror (detestable idol) of the sons of Ammon. ⁸ And he did the same for all of his foreign wives, who burned incense and sacrificed to their gods.
