2 Samuel 18:9-15

9Then Absalom happened to come across David’s men. Now as Absalom was riding on his mule, it went under the branches of a large oak tree. His head got caught in the oak and he was suspended in midair, while the mule he had been riding kept going.

10When one of the men saw this, he reported it to Joab saying, “I saw Absalom hanging in an oak tree.

11Joab replied to the man who was telling him this, “What! You saw this? Why didn’t you strike him down right on the spot? I would have given you ten pieces of silver and a commemorative belt!”

12The man replied to Joab, “Even if I were receiving a thousand pieces of silver, I would not strike the king’s son! In our very presence the king gave this order to you and Abishai and Ittai, ‘Protect the young man Absalom for my sake.’

13If I had acted at risk of my own life – and nothing is hidden from the king! – you would have abandoned me.”

14Joab replied, “I will not wait around like this for you!” He took three spears in his hand and thrust them into the middle of Absalom while he was still alive in the middle of the oak tree.

15Then ten soldiers who were Joab’s armor bearers struck Absalom and finished him off.
