II Samuel 18:14

Joab replied, "Not so will I wait before thee," i.e., I will not leave the thing to thee. He then took three staffs in his hand, and thrust them into Absalom's heart. שׁבטים is rendered by the lxx and Vulgate, βέλη, lanceas; and Thenius would adopt שׁלחים accordingly, as an emendation of the text. But in the earlier Hebrew שׁלח only occurs in poetical writings in the sense of a missile or dart (Job 33:18; Job 36:12; Joe 2:8); and it is not till after the captivity that we find it used to denote a weapon generally. There is no necessity, however, for altering the text. Joab caught up in his hurry the first thing that he found, namely pointed staff, and pierced Absalom with them to the heart. This explains the reason for his taking three, whereas one javelin or dart would have been sufficient, and also the fact that Absalom was not slain, notwithstanding their being thrust at his heart. The last clause of the verse belongs to what follows: "Still living (i.e., as he was still alive) in the midst of the terebinth, ten young men, Joab's armour-bearers, surrounded him, and smote him to death."

This chapter puts a period to Absalom's rebellion and life, and so makes way for David to his throne again, whither the next chapter brings him back in peace and triumph. We have here, I. David's preparations to engage the rebels (Sa2 18:1-5). II. The total defeat of Absalom's party and their dispersion (Sa2 18:6-8). III. The death of Absalom, and his burial (Sa2 18:9-18). IV. The bringing of the tidings to David, who tarried at Mahanaim (Sa2 18:19-32). V. His bitter lamentation for Absalom (Sa2 18:33).

18:14 plunged them into Absalom’s heart: Earlier, Joab had played the role of reconciler between David and Absalom (ch 14). It is possible Joab believed that allowing Absalom to live would only invite ongoing trouble for David and for himself. (Absalom had appointed Amasa, Joab’s first cousin, to fill Joab’s position as commander of Israel’s army; see 17:25.)
