1 Kings 11:4-6

New Revised Standard Version Catholic Edition

⁴ For when Solomon was old, his wives turned away his heart after other gods; and his heart was not true to the Lord his God, as was the heart of his father David. ⁵ For Solomon followed Astarte the goddess of the Sidonians, and Milcom the abomination of the Ammonites. ⁶ So Solomon did what was evil in the sight of the Lord, and did not completely follow the Lord, as his father David had done.
