1 Kings 11:4 KJV

2Of the nations concerning which the LORD said unto the children of Israel, Ye shall not go in to them, neither shall they come in unto you: for surely they will turn away your heart after their gods: Solomon clave unto these in love.

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

4For 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.

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

6And Solomon did evil in the sight of the LORD, and went not fully after the LORD, as did David his father.
