171 Moreover Ahithophel said to Absalom, "Now let me choose twelve thousand men, and I will arise and pursue David tonight. 2 I will come upon him while he is weary and weak, and make him afraid. And all the people who are with him will flee, and I will strike only the king. 3 Then I will bring back all the people to you. When all return except the man whom you seek, all the people will be at peace." 4 And the saying pleased Absalom and all the elders of Israel. 5 Then Absalom said, "Now call Hushai the Archite also, and let us hear what he says too." 6 And when Hushai came to Absalom, Absalom spoke to him, saying, "Ahithophel has spoken in this manner. Shall we do as he says? If not, speak up." 7 So Hushai said to Absalom: "The advice that Ahithophel has given is not good at this time. 8 For," said Hushai, "you know your father and his men, that they are mighty men, and they are enraged in their minds, like a bear robbed of her cubs in the field; and your father is a man of war, and will not camp with the people.

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.
