1 Kings 11:5 (KJV)

But king Solomon loved many strange women, together with the daughter of Pharaoh, women of the Moabites, Ammonites, Edomites, Zidonians, and Hittites:

Of 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.

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

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.

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

Then did Solomon build an high place for Chemosh, the abomination of Moab, in the hill that is before Jerusalem, and for Molech, the abomination of the children of Ammon.

And likewise did he for all his strange wives, which burnt incense and sacrificed unto their gods.

And the LORD was angry with Solomon, because his heart was turned from the LORD God of Israel, which had appeared unto him twice,

And had commanded him concerning this thing, that he should not go after other gods: but he kept not that which the LORD commanded.
