2 Samuel 18:9-18

⁹ Absalom ran into David's men, but was out in front of them riding his mule, when the mule ran under the branches of a huge oak tree. Absalom's head was caught in the oak and he was left dangling between heaven and earth, the mule running right out from under him. ¹⁰ A solitary soldier saw him and reported it to Joab, "I just saw Absalom hanging from an oak tree!" ¹¹ Joab said to the man who told him, "If you saw him, why didn't you kill him then and there? I'd have rewarded you with ten pieces of silver and a fancy belt." ¹² The man told Joab, "Even if I'd had a chance at a thousand pieces of silver, I wouldn't have laid a hand on the king's son. We all heard the king command you and Abishai and Ittai, 'For my sake, protect the young man Absalom.' ¹³ Why, I'd be risking my life, for nothing is hidden from the king. And you would have just stood there!" ¹⁴ Joab said, "I can't waste my time with you." He then grabbed three knives and stabbed Absalom in the heart while he was still alive in the tree; ¹⁵ by then Absalom was surrounded by ten of Joab's armor bearers; they hacked away at him and killed him. ¹⁶ Joab then blew the ram's horn trumpet, calling off the army in its pursuit of Israel. ¹⁷ They took Absalom, dumped him into a huge pit in the forest, and piled an immense mound of rocks over him. Meanwhile the whole army of Israel was in flight, each man making his own way home. ¹⁸ While alive, Absalom had erected for himself a pillar in the Valley of the King, "because," he said, "I have no son to carry on my name." He inscribed the pillar with his own name. To this day it is called "The Absalom Memorial."
