2 Samuel 13:21

was very wroth The Sept. and the ordinary text of the Vulgate add, "and he vexed not the spirit of Amnon his son, because he loved him, because he was his firstborn," i.e. in spite of his anger he did not punish or even rebuke the offence, though the legal penalty of his crime was death. David's indulgent treatment of his sons was a fruitful source of mischief (cp. 1 Kings 1:6), and led in this case to the murder of Amnon, and ultimately to Absalom's rebellion. The consciousness of his own guilt moreover weakened his hands for dealing with Amnon's offence.
