2 Samuel 18:12-13

12But the man said to Joab, “Even if I had 1,000 pieces of silver in my hand, I would not raise my hand against the king’s son; for in our hearing the king charged you, Abishai and Ittai saying, ‘Watch over the young man Absalom for me.’

13Otherwise, I would have betrayed his soul—and nothing stays hidden from the king—and you yourself would have stood aloof.”
