2 Samuel 18:11-15

11And Joab said to the man that told him, And, behold, thou sawest him, and why didst thou not smite him there to the ground? and I would have given thee ten shekels of silver, and a belt. 12And the man said to Joab, Though I should receive a thousand shekels of silver in my hand, yet would I not put forth my hand against the king’s son: for in our hearing the king charged thee and Abishai and Ittai, saying, Beware that none touch the young man Absalom.12 13Otherwise I should have wrought falsehood against my own life: for there is no matter hid from the king, and thou thyself wouldest have set thyself against me . 14Then said Joab, I may not tarry thus with thee. And he took three spears in his hand, and thrust them through the heart of Absalom, while he was yet alive in the midst of the oak.34 15And ten young men that bore Joab’s armour surrounded and smote Absalom, and slew him.
