Then Absalom and all of the men of Israel said, “The advice of Hushai the Arkite is better than the advice of Ahithophel.” For the Lord had decided to undermine the prudent advice of Ahithophel, so that the Lord might bring calamity to Absalom.
When Ahithophel realized that his advice was not followed, he saddled his donkey and returned to his house in his own city. He gave instruction to his household, then he hanged himself and died; he was interred in the tomb of his father.
therefore, behold, I will once again do a marvelous work among this people, even a marvelous work and a wonder; for the wisdom of their wise men shall perish, and the understanding of their prudent men shall be hidden.
He has confirmed His words, which He had spoken against us and against our judges who judged us, by bringing on us great calamity. For under the whole heaven there has not been done such as has been done to Jerusalem.
