2 Samuel 18:12-13

12“I would not kill the king’s son for even a thousand pieces of silver,” the man replied to Joab. “We all heard the king say to you and Abishai and Ittai, ‘For my sake, please spare young Absalom.’

13And if I had betrayed the king by killing his son—and the king would certainly find out who did it—you yourself would be the first to abandon me.”
