14 Then said Joab, I may not tarry thus with thee. And he took three spears in his hand, and thrust them into Absalom's body, while he was yet alive in the midst of the terebinth. 15 And ten young men that bore Joab's armour surrounded and smote Absalom, and killed him.
Matthew Henry's Commentary on 2 Samuel 18:14-15
Commentary on 2 Samuel 18:9-18
(Read 2 Samuel 18:9-18)
Let young people look upon Absalom, hanging on a tree, accursed, forsaken of heaven and earth; there let them read the Lord's abhorrence of rebellion against parents. Nothing can preserve men from misery and contempt, but heavenly wisdom and the grace of God.
