171 Now Ahithophel urged Absalom, "Let me choose 12,000 men to start out after David tonight. 2 I will catch up with him while he is weary and discouraged. He and his troops will panic, and everyone will run away. Then I will kill only the king, 3 and I will bring all the people back to you as a bride returns to her husband. After all, it is only one man's life that you seek. Then you will be at peace with all the people." 4 This plan seemed good to Absalom and to all the elders of Israel. 5 But then Absalom said, "Bring in Hushai the Arkite. Let's see what he thinks about this." 6 When Hushai arrived, Absalom told him what Ahithophel had said. Then he asked, "What is your opinion? Should we follow Ahithophel's advice? If not, what do you suggest?" 7 "Well," Hushai replied to Absalom, "this time Ahithophel has made a mistake. 8 You know your father and his men; they are mighty warriors. Right now they are as enraged as a mother bear who has been robbed of her cubs. And remember that your father is an experienced man of war. He won't be spending the night among the troops.

Here was a wonderful effect of Divine Providence blinding Absalom's mind and influencing his heart, that he could not rest in Ahithophel's counsel, and that he should desire Hushai's advice. But there is no contending with that God who can arm a man against himself, and destroy him by his own mistakes and passions. Ahithophel's former counsel was followed, for God intended to correct David; but his latter counsel was not followed, for God meant not to destroy him. He can overrule all counsels. Whatever wisdom or help any man employs or affords, the success is from God alone, who will not let his people perish.
