2 Samuel 18:9-15

9Absalom happened to come face to face with some of David’s men. He was riding on a mule, and the mule went under the tangled branches of a large tree. Absalom’s head became caught in the tree. So he was left hanging  in midair when the mule that was under him ran away.

10A man who saw this told Joab, “I saw Absalom hanging in a tree.”

11“What! You saw that!” Joab said to the man who told him. “Why didn’t you strike him to the ground? Then I would have felt obligated to give you four ounces of silver and a belt.”

12But the man told Joab, “Even if I felt the weight of 25 pounds of silver in my hand, I wouldn’t raise my hand against the king’s son. We heard the order the king gave you, Abishai, and Ittai: ‘Protect the young man Absalom for my sake.’

13If I had done something treacherous to him, would you have stood by me? Like everything else, it wouldn’t stay hidden from the king.”

14Then Joab said, “I shouldn’t waste time with you like this.” He took three sharp sticks and plunged them into Absalom’s heart while he was still alive in the tree.

15Then ten of Joab’s armorbearers surrounded Absalom, attacked him, and killed him.
