2 Samuel 15:3

For nothing is so necessary for the proper conduct of affairs as prudence; and there is no greater hindrance to prudence than wickedness, and malice, and hollowness. Look at bilious persons, how unsightly they are, with all their bloom withered away. How weak they are, and puny, and unfit for anything. So also are souls of this nature. What else is wickedness, but a jaundice of the soul? Wickedness then has no strength in it, indeed it has not. Have ye a mind that I again make what I am saying plain to you by an instance, by setting before you the portraits of a treacherous and a guileless man? Absalom was a treacherous man, and "stole all men's hearts." And observe how great was his treachery. "He went about," it saith, "and said, 'Hast thou no judgment?'" wishing to conciliate every one to himself. But David was guileless. What then? Look at the end of them both, look, how full of utter madness was the former! For inasmuch as he looked solely to the hurt of his father, in all other things he was blinded. But not so David. For "he that walketh uprightly, walketh surely"; and reasonably; he is one that manages nothing over-subtilely, the man who devises no evil.

Moreover, due measure befits even our words and instructions, that it may not seem as though there was either too great mildness or too much harshness. Many prefer to be too mild, so as to appear to be good. But it is certain that nothing feigned or false can bear the form of true virtue; no, it cannot even last. At first it flourishes; then, as time goes on, like a flower it fades and passes away, but what is true and sincere has a deep root.…Absalom was king David's son, known for his beauty, of splendid appearance and in the heyday of youth; so that no other man like him was found in Israel. He was without a blemish from the sole of his foot to the crown of his head. He had his own chariot and horses and fifty men to run before him. He rose at early dawn and stood before the gate in the way, and whoever he knew to be seeking the judgment of the king, he called to himself, saying … "Is there no one given to you by the king to hear you? Who will make me a judge? And whosoever will come to me, that has need of judgment, I will give him justice." With such words he cajoled them. And when they came to make obeisance to him, stretching forth his hand he took hold of them and kissed them. So he turned the hearts of all to himself. For flattery of this sort quickly finds its way to touch the very depths of the heart.
