2 Samuel 18:12-13

12But the man replied, ‘I would never hurt the king's son, even for a gift of 1,000 silver coins. We all heard the king give this command to you, Abishai and Ittai. He said, “Keep the young man Absalom safe, because he is my son.”

13If I had killed Absalom, my own life would be in danger. The king knows everything that happens! You would not have tried to save me from the king's punishment.’
