2 Samuel 16:17

Is this thy kindness to thy friend? Doth this action answer that profession of friendship which thou hast hitherto made to him? He speaks thus only to try him. He does not say, To my father, for that question would have reflected a heavier reproach upon himself, who had forsaken not only a friend, but his own father, and even forced him away. Or, perhaps, by saying, Thy friend, he meant to insinuate, that David was a friend to Hushai, and to strangers, but not to his own son, whom by severity he had provoked to take this course; and therefore he doth not vouchsafe to call him his father.
