2 Samuel 16:15-23

And Absalom, and all the people, the men of Israel, came to Jerusalem, and Ahithophel with him. And it came to pass, when Hushai the Archite, David’s friend, was come unto Absalom, that Hushai said unto Absalom, Long live the king, Long live the king. And Absalom said to Hushai, Is this thy kindness to thy friend? why wentest thou not with thy friend? And Hushai said unto Absalom, Nay; but whom Jehovah, and this people, and all the men of Israel have chosen, his will I be, and with him will I abide. And again, whom should I serve? should I not serve in the presence of his son? as I have served in thy father’s presence, so will I be in thy presence. Then said Absalom to Ahithophel, Give your counsel what we shall do. And Ahithophel said unto Absalom, Go in unto thy father’s concubines, that he hath left to keep the house; and all Israel will hear that thou art abhorred of thy father: then will the hands of all that are with thee be strong. So they spread Absalom a tent upon the top of the house; and Absalom went in unto his father’s concubines in the sight of all Israel. And the counsel of Ahithophel, which he gave in those days, was as if a man inquired at the oracle of God: so was all the counsel of Ahithophel both with David and with Absalom.
