16 When David's friend Hushai the Arkite arrived, he went immediately to see Absalom. "Long live the king!" he exclaimed. "Long live the king!" 17 "Is this the way you treat your friend David?" Absalom asked him. "Why aren't you with him?" 18 "I'm here because I belong to the man who is chosen by the Lord and by all the men of Israel," Hushai replied.

Commentary on 2 Samuel 16:15-23
(Read 2 Samuel 16:15-23)
The wisest counsellors of that age were Ahithophel and Hushai: Absalom thinks himself sure of success, when he has both; on them he relies, and consults not the ark, though he had that with him. But miserable counsellors were they both. Hushai would never counsel him to do wisely. Ahithophel counselled him to do wickedly; and so did as effectually betray him, as he did, who was designedly false to him: for they that advise men to sin, certainly advise them to their hurt. After all, honesty is the best policy, and will be found so in the long run. Ahithophel gave wicked counsel to Absalom; to render himself so hateful to his father, that he would never be reconciled to him; this cursed policy was of the devil. How desperately wicked is the human heart!
