2 Samuel 18:12-13

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.”
