2 Samuel 18:14

Then said Joab, I may not tarry thus with thee. And he took three darts in his hand, and thrust them through the heart of Absalom, while he was yet alive in the midst of the oak.

He took three darts, х shªbaaTiym (H7626)] - small rods with iron points; lances.

And thrust them through the heart of Absalom. The deed, partially done by Joab, was completed by his body-guard. Being a violation of the expressed wish, as well as of all the fond paternal feelings of David, it must have been deeply offensive to the king, nor was it ever forgotten (1 Kings 2:5); and yet there is the strongest reason for believing that Joab, in doing it, was actuated by a sincere regard to the interests of David, both as a man and a monarch.
