2 Samuel 18:11-13

11So Joab said to the man who told him, “You just saw him! And why did you not strike him there to the ground? I would have given you ten shekels of silver and a belt.”

12But the man said to Joab, “Though I were to receive a thousand shekels of silver in my hand, I would not raise my hand against the king’s son. For in our hearing the king commanded you and Abishai and Ittai, saying, ‘Beware lest anyone touch the young man Absalom!’

13Otherwise I would have dealt falsely against my own life. For there is nothing hidden from the king, and you yourself would have set yourself against me.”
