1 Kings 11:4-6

Revised Standard Version

⁴ For when Solomon was old his wives turned away his heart after other gods; and his heart was not wholly true to the Lord his God, as was the heart of David his father. ⁵ For Solomon went after Ash′toreth the goddess of the Sido′nians, and after Milcom the abomination of the Ammonites. ⁶ So Solomon did what was evil in the sight of the Lord, and did not wholly follow the Lord, as David his father had done.
