1 Kings 11:3-5

Revised Geneva Translation

³ And he had seven hundred wives (princesses) and three hundred concubines. And his wives perverted his heart.

⁴ For when Solomon was old, his wives turned his heart after other gods, so that his heart was not perfect with the LORD his God, as the heart of David his father.

⁵ For Solomon followed Ashtoreth, the god of the Sidonians, and Milcom, the abomination of the Ammonites.
