14 Then Joab said, I would have made it safe for you. And he took three spears in his hand, and put them through Absalom's heart, while he was still living, in the branches of the tree. 15 And ten young men, servants of Joab, came round Absalom and put an end to 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.
