2. Samuel 13:32

Then Jonadab, the same person who had helped Amnon to commit his crime, said, "Let not my lord say (or think) that they have slain all the young men the king's sons, but Amnon alone is dead; for it was laid upon the mouth of Absalom from the day that he forced his sister Tamar." The meaning is either "they might see it (the murder of Amnon) by his mouth," or "they might gather it from what he said." שׂימה היתה: it was a thing laid down, i.e., determined (vid., Exo 21:13). The subject, viz., the thing itself, or the intended murder of Amnon, may easily be supplied from the context. אם כּי is undoubtedly used in the sense of "no but." The negation is implied in the thought: Let the king not lay it to heart, that they say all the king's sons are dead; it is not so, but only Amnon is dead. Jonadab does not seem to speak from mere conjecture; he is much too sure of what he says. He might possibly have heard expressions from Absalom's lips which made him certain as to how the matter stood. Sa2 13:34 "And Absalom fled." This statement follows upon Sa2 13:29. When the king's sons fled upon their mules, Absalom also took to flight. Sa2 13:30-33 are a parenthesis, in which the writer describes at once the impression made upon the king and his court by the report of what Absalom had done. The apparently unsuitable position in which this statement is placed may be fully explained from the fact, that the flight of Absalom preceded the arrival of the rest of the sons at the king's palace. The alteration which Bttcher proposes to make in the text, so as to remove this statement altogether on account of its unsuitable position, is proved to be inadmissible by the fact that the account of Absalom's flight cannot possibly be left out, as reference is made to it again afterwards (Sa2 13:3…

The righteous God had lately told David, by Nathan the prophet, that, to chastise him for his son in the matter of Uriah, he would "raise up evil against him out of his own house," (Sa2 12:11). And here, in the very next chapter, we find the evil beginning to rise; henceforward he was followed with one trouble after another, which made the latter part of his reign less glorious and pleasant than the former part. Thus God chastened him with the rod of men, yet assured him that his "loving-kindness he would not utterly take away." Adultery and murder were David's sins, and those sins among his children (Amnon defiling his sister Tamar, and Absalom murdering his brother Amnon) were the beginnings of his punishment, and the more grievous because he had reason to fear that his bad example might help to bring them to these wickednesses. In this chapter we have, I. Amnon ravishing Tamar, assisted in his plot to do it by Jonadab his kinsman, and villainously executing it (v. 1-20). II. Absalom murdering Amnon for it (v. 21-39). Both were great griefs to David, and the more because he was unwittingly made accessory to both, by sending Tamar to Amnon and Amnon to Absalom.
