1 Kings 11:2-4

MKJV(i) 2 of the nations which Jehovah had said to the sons of Israel, You shall not go in to them, and they shall not go in to you; surely they will turn away your heart after their gods. Solomon clung to these in love. 3 And he had seven hundred wives, princesses, and three hundred concubines. And his wives turned away his heart. 4 For it happened when Solomon was old, his wives turned away his heart after other gods. And his heart was not perfect with Jehovah his God, as was the heart of David his father.
