Ambrose of Milan, on 2Sam 16:9

“And Abisai the son of Sarvia said to the king: Why should this dead dog curse my lord the king? I will go, and cut off his head.”

“What need is there to be troubled when we hear abuse? Why do we not imitate him who says, "I was dumb and humbled myself, and kept silence even from good words." Or did David only say this, and not act up to it? No, he also acted up to it. For when Shimei the son of Gera reviled him, David was silent; and although he was surrounded with armed men he did not return the abuse, nor seek revenge: no, even when the son of Zeruiah spoke to him, because he wished to take vengeance on him, David did not permit it. He went on as though dumb and humbled; he went on in silence; nor was he disturbed, although called a bloody man, though he was conscious of his own gentleness. He therefore was not disturbed by insults, for he had full knowledge of his own good works.He, then, who is quickly roused by wrong makes himself seem deserving of insult, even while he wishes to be shown not to deserve it. He who despises wrongs is better off than he who grieves over them. For he who despises them looks down on them, as though he doesn't feel them; but he who grieves over them is tormented, just as though he actually felt them.”
