But when King David heard - To this verse the Septuagint add the following words: Και ουκ ελυπησε το πνευμα Αμνων του υἱου αυτου, ὁτι ηγαπα αυτον, ὁτι πρωτοτοκος αυτου ην ; "But he would not grieve the soul of Amnon his son, for he loved him, because he was his first-born." The same addition is found in the Vulgate and in Josephus, and it is possible that this once made a part of the Hebrew text.

The Septuagint adds, what is a good explanation, “but he did not vex the spirit of Amnon his son, because he loved him, because he was his first-born.” This want of justice in David‘s conduct, and favoritism to Amnon, probably rankled in Absalom‘s heart, and was the first seed of his after rebellion.

Observe the aggravations of Absalom's sin: he would have Ammon slain, when least fit to go out of the world. He engaged his servants in the guilt. Those servants are ill-taught who obey wicked masters, against God's commands. Indulged children always prove crosses to godly parents, whose foolish love leads them to neglect their duty to God.
