The sin of idolatry: As Solomon grew old, his wives turned his heart after other gods, and his heart was not fully devoted to the LORD his God. 1 Kings 11:4
Solomon's idolatry in the Bible is a demonstration that no one, no matter how spiritually elevated, can be completely good, and that ultimately goodness belongs only to God. In his first appearance to Solomon at the sacred site of Gibeon, God granted the King a heart that knows how to listen; that is, He gave the great ruler a heart full of wisdom, understanding, and spiritual discernment, so that he could finish the Temple of Jerusalem and follow in the footsteps of David, who had so pleased God. And so it was, Solomon did divine justice, established peace, wrote many books to instruct his people, and made all the Israelites prosper, who were able to see how greatly God had blessed Solomon's Kingdom.
But in time, the unexpected happened. And Solomon committed an error similar to that committed by his father, King David, when he fell madly in love with Bathsheba, an extremely beautiful woman. And the Book of Kings relates that Solomon had many foreign wives despite God's counsel warning of this danger with these words: "King Solomon, however, loved many foreign women besides Pharaoh's daughter—Moabites, Ammonites, Edomites, Sidonians and Hittites" 1 Kings 11:1. Perhaps this was because Solomon, in order to establish peace, had to accept political marriages with other foreign dynasties, but this was the seed of the sin of idolatry in Solomon. Solomon, like David, had a weakness for women. And so the First Book of Kings relates that Solomon did what is evil in the sight of God: "As Solomon grew old, his wives turned his heart after other gods, and his heart was not fully devoted to the LORD his God" 1 Kings 11:4. Solomon, despite his great wisdom, erected places dedicated to other gods in the city of Jerusalem. And so Solomon's heart was not fully perfect before God. As a consequence of this, God announced to Solomon that his kingdom after his death would be divided into two, one part for one of his sons and the other for one of his servants.
This story leaves Bible readers with the spiritual reflection that even the wisest men are subject to the weaknesses of ordinary people and thus commit sin. And that is why even the wisest should always practice humility and develop the ability to learn from their own mistakes, because ultimately only God is the wisest and most perfect being of the universe.
