2 Samuel 17:5 - Joseph Benson’s Commentary on the Old and New Testaments

Then said Absalom, Call now Hushai A wonderful effect of Divine Providence, influencing his heart, that he could not rest in Ahithophel's counsel, though it was so evidently wise, and approved by the general consent of his whole party; and that he should desire Hushai's advice, though neither his reputation for wisdom was equal to Ahithophel's, nor had he yet given any one proof of his fidelity to Absalom. But there is no contending with that God who can arm a man against himself, and destroy him by his own mistakes and passions.
