18 Now Absalom in his lifetime had taken and reared up for himself the pillar, which is in the king's dale; for he said, I have no son to keep my name in remembrance: and he called the pillar after his own name; and it is called Absalom's monument, unto this day.
Matthew Henry's Commentary on 2 Samuel 18:18
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.
