18 Now Ab'salom in his lifetime had taken and set up for himself the pillar which is in the King's Valley, for he said, "I have no son to keep my name in remembrance"; he called the pillar after his own name, and it is called Ab'salom's monument to 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.
