II Samuel 18:2, 14-15

Then David sent out one third of the people under the hand of Joab, one third under the hand of Abishai the son of Zeruiah, Joab’s brother, and one third under the hand of Ittai the Gittite. And the king said to the people, “I also will surely go out with you myself.”

Then Joab said, “I cannot linger with you.” And he took three spears in his hand and thrust them through Absalom’s heart, while he was still alive in the midst of the terebinth tree. And ten young men who bore Joab’s armor surrounded Absalom, and struck and killed him.
