II Samuel 13:21

Amnon's Incest, and Absalom's Fratricide - 2 Samuel 13 The judgments threatened to king David in consequence of his sin with Bathsheba soon began to fall upon him and upon his house, and were brought about by sins and crimes on the part of his own sons, for which David was himself to blame, partly because of his own indulgence and want of discipline, and partly because of the bad example that he had set them. Having grown up without strict paternal discipline, simply under the care of their different mothers, who were jealous of one another, his sons fancied that they might gratify their own fleshly lusts, and carry out their own ambitious plans; and from this there arose a series of crimes, which nearly cost the king his life and throne. Amnon, David's eldest son, led the way with his forcible violation of his step-sister Tamar (vv. 1-22). The crime was avenged by her own brother Absalom, who treacherously assassinated Amnon, in consequence of which he was obliged to flee to Geshur and take refuge with his father-in-law (vv. 23-39).

What Solomon says of the beginning of strife is as true of the beginning of all sin, it is as the letting forth of water; when once the flood-gates are plucked up, an inundation follows; one mischief begets another, and it is hard to say what shall be in the end thereof. I. We are here told how David resented the tidings of Amnon's sin: He was very wroth, Sa2 13:21. So he had reason to be, that his own son should do such a wicked thing and draw him to be accessory to it. It would be a reproach to him for not giving him a better education; it would be a blot upon his family, the ruin of his daughter, a bad example to his kingdom, and a wrong to his son's soul. But was it enough for him to be angry? He ought to have punished his son for it, and have put him to open shame; both as a father and as a king he had power to do it. But the Septuagint here adds these words: But he saddened not the spirit of his son Amnon, because he loved him, because he was his first-born. He fell into Eli's error, whose sons made themselves vile, and he frowned not on them. If Amnon was dear to him, his punishing him would have been so much the greater punishment to himself for his own uncleanness. But he cannot bear the shame those must submit to who correct that in others which they are conscious of in themselves, and therefore his anger must serve instead of his justice; and this hardens sinners, Ecc 8:11. II. How Absalom resented it. He resolves already to do the part of a judge in Israel; and, since his father will not punish Amnon, he will, from a principle, not of justice or zeal for virtue, but of revenge, because he reckons himself affronted in the abuse done to his sister. Their mother was daughter to a heathen prince (Sa2 3:3), which perhaps they were upbraided with sometimes by thei…

13:21 King David . . . was very angry: But he apparently never punished Amnon—as in the Dead Sea Scrolls and Greek version, which add that it was because he loved Amnon. Another possibility is that as an adulterer himself (see 11:1–12:24), David considered himself in no position to punish his son’s sexual sin. A third possibility is that David thought this was God’s “eye for an eye” punishment for his own sexual indiscretion.
