“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.”
1 Kings 11:4

The wisest man in all human history was still foolish enough to abandon God to please women.
Not only did Solomon have 1000 wives and concubines, but followed many of them into worshiping false gods.
This exemplifies 2 Cor 6:14 – do not be unequally yoked with unbelievers.
Had Solomon obeyed God, his greatness would have been even more than it was.
In the end, Solomon was just a man; a wretched sinner that needed God.
So much the more do I.
