David's Wrath and Absalom's Silent Hatred

2 Samuel 13:21-22

And when king David heard of these things he was exceedingly grieved: and he would not afflict the spirit of his son Ammon, for he loved him, because he was his firstborn.

But Absalom spoke not to Ammon neither good nor evil: for Absalom hated Ammon because he had ravished his sister Thamar.
