2 Samuel 18:11-15

11Then Joab said to his informant, “Look here, you saw him, so why didn’t you strike him there to the ground? I would have given you ten pieces of silver and a belt!”

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.”

14“I won’t wait for you!” Joab said. So he took three darts in his hand and thrust them through Absalom’s heart while he was yet alive in the midst of the oak.

15Then ten young men who were Joab’s armor-bearers surrounded Absalom, struck and finished him off.
