2 Samuel 19

2 Samuel 19:1

Augustine of Hippo: But when king David had suffered this injury at the hands of his impious and unnatural son, he not only bore with him in his mad passion but mourned over him in his death. He certainly was not caught in the meshes of carnal jealousy, seeing that it was not his own injuries but the sins of his son that moved him. For it was on this account he had given orders that his son should not be slain if he were conquered in battle, that he might have a place of repentance after he was subdued. When he was baffled in this design, he mourned over his son’s death, not because of his own loss but because he knew to what punishment so impious an adulterer and parricide had been hurried. — CHRISTIAN INSTRUCTION 3.21

2 Samuel 19:27

Gregory the Dialogist: Why do you marvel, Peter? for the reason why we are deceived is, because we be men. What? have you forgotten how David, who usually had the spirit of prophecy, pronounced sentence against innocent Mephibosheth, the son of Jonathan, when he gave credit to the lying words of his servant Siba? Which thing notwithstanding because it was done by David, we both believe to be just in the secret judgment of God, and yet by human reason how it was just we cannot perceive. What marvel then is it, if we, that be not prophets, be sometimes by lying tongues abused, and otherwise transported than charity and justice would: for it is much to be considered, that every Bishop hath his mind troubled with a world of business, and it cannot be, when the mind is distracted about many things, but that it is the less able sufficiently to examine those that be particular, and so much the sooner is he deceived in some special case, by how much he is busied with the multitude of many. — Dialogues, Book 1, Chapter 4
