2 Samuel 17:5

A wonderful effect of Divine Providence, blinding his mind, and influencing his heart, that he could not rest in Ahithophel's counsel, though it was so evidently wise, and good, 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 as Ahithophel had done; nor was he so fixed by his interest to him as Ahithophel was; and though there wanted not just cause to suspect him and his counsel too. But there is no contending with that God who can arm a man against himself, and destroy him by his own mistakes and passions, without any other help.
