1 Kings 11:3-5

BRG Bible

³ And he had seven hundred wives, princesses, and three hundred concubines: and his wives turned away his heart.

⁴ For 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 the Lord his God, as was the heart of David his father.

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