4 In Solomon's old age, they turned his heart to worship other gods instead of being completely faithful to the Lord his God, as his father, David, had been. 5 Solomon worshiped Ashtoreth, the goddess of the Sidonians, and Molech, the detestable god of the Ammonites. 6 In this way, Solomon did what was evil in the Lord 's sight; he refused to follow the Lord completely, as his father, David, had done.

Matthew Henry's Commentary on 1 Kings 11:4-6

Commentary on 1 Kings 11:1-8

(Read 1 Kings 11:1-8)

There is not a more melancholy and astonishing instance of human depravity in the sacred Scriptures, than that here recorded. Solomon became a public worshipper of abominable idols! Probably he by degrees gave way to pride and luxury, and thus lost his relish for true wisdom. Nothing forms in itself a security against the deceitfulness and depravity of the human heart. Nor will old age cure the heart of any evil propensity. If our sinful passions are not crucified and mortified by the grace of God, they never will die of themselves, but will last even when opportunities to gratify them are taken away. Let him that thinks he stands, take heed lest he fall. We see how weak we are of ourselves, without the grace of God; let us therefore live in constant dependence on that grace. Let us watch and be sober: ours is a dangerous warfare, and in an enemy's country, while our worst foes are the traitors in our own hearts.
