Absalom Enters Jerusalem; Hushai's Ploy

2 Samuel 16:15-19

But Absalom and all his people came into Jerusalem, and Achitophel was with him.

And when Chusai the Arachite, David's friend, was come to Absalom, he said to him: God save thee, O king, God save thee, O king.

And Absalom said to him, Is this thy kindness to thy friend? Why wentest thou not with thy friend?

And Chusai answered Absalom: Nay: for I will be his, whom the Lord hath chosen, and all this people, and all Israel, and with him will I abide.

Besides this, whom shall I serve? is it not the king's son? as I have served thy father, so will I serve thee also.
