Where did Solomon's wisdom begin to deviate from God's commandments?

The starting point of Solomon's deviation is clearly identified in the opening of 1 Kings 11: he "loved many foreign women, together with the daughter of Pharaoh, women of the Moabites, Ammonites, Edomites, Sidonians, and Hittites." This was a direct violation of God's command, for Israel had been warned that these nations "will turn away your heart after their gods." Solomon's extraordinary wisdom, which had been granted by God, did not protect him from this fundamental disobedience. Polished intellect and spiritual fidelity are not the same thing; one can be gifted with discernment and still choose to ignore the plain word of the Lord.

The text is precise about the mechanism of the fall: "his wives turned away his heart." The drift was not sudden idolatry but a gradual erosion. First came the marriages, then the building of high places for Chemosh and Molech, and finally open service to Ashtoreth and Milcom. Verse 6 makes the verdict inescapable: "Solomon did that which was evil in the sight of Jehovah, and went not fully after Jehovah, as did David his father." This is the classic biblical pattern in which compromise in one commanded area leads to broader unfaithfulness.

For this reason, the question is not really about when Solomon lost his intelligence but about when his obedience collapsed. The answer is that obedience collapsed at the point of marriage to foreign women, the very first act recorded in the chapter. The tension between wisdom and obedience is not theoretical here: Solomon possessed the greatest wisdom ever granted to a king, yet the chapter shows that wisdom without sustained obedience to God's specific commands cannot preserve a person's heart.

The passage does not present Solomon as a man who suddenly lost his mind or his skill. His wisdom itself is never said to vanish. Rather, the chapter treats wisdom and obedience as two separate things, and shows that the second can collapse while the first remains. The verse-by-verse answer to the question is therefore political and marital compromise: the very first action named, loving foreign women against God's command, is the wedge that opens the door to the idolatry that follows. Readers should not look for a later, more dramatic moment as the true turning point; the text identifies the marriages as the deviation.

The chapter also gives the divine perspective: God had appeared to Solomon twice and commanded him not to go after other gods (11:9-10). The deviation is therefore not ignorance but conscious disregard. The consequence is spelled out almost immediately: the kingdom will be torn away, though not wholly in Solomon's lifetime, for the sake of David.
