SEV Biblia, Chapter 13:21
¶ Y luego que el rey David oyó todo esto, fue muy enojado.
Clarke's Bible Commentary - 2 Samuel 13:21
Verse 21. But when King David heard] To this verse the Septuagint add the following words: kai ouk eluphse to pneuma amnwn tou uiou autou, oti hgapa auton, oti prwtotokov autou hn; "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.
John Gill's Bible Commentary
Ver. 21. But when King David heard of all these things , etc.] Of Amnon’s ravishing Tamar, and turning her out of doors in that inhuman manner he did, and of her distress upon it: he was very wroth ; with Amnon; but we read not of any reproof he gave him, nor of any punishment inflicted on him by him. Abarbinel thinks the reason why he was not punished was because his sin was not cognizable by a court of judicature, nor was punishable by any way, or with any kind of death inflicted by the sanhedrim, as stoning, burning, etc. nor even by scourging, because there were no witnesses; but the punishment of it was cutting off, i.e. by the hand of God. The Jews say a law was made on this, that virgins or unmarried persons should not be alone; for if this was done to the daughter of a king, much more might it be done to the daughter of a private man; and if to a modest person, much more to an impudent one.
Matthew Henry Commentary
Verses 21-29 - 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, agains God's commands. Indulged children always prove crosses to godl parents, whose foolish love leads them to neglect their duty to God.
