מדרש על שמואל ב 20:8

Six people were similar to the first man, and they were all slain. They were: Samson with his might, and he was slain; Saul with his stature, and he was slain; Asahel with his swiftness, and he was slain; Josiah with his nostrils, and he was slain through his nostrils; Zedekiah with his eyes, and he was slain through his eyes; Absalom with his hair, and he was killed through his hair. Absalom was a mighty hero in battle, and his sword was bound upon his loins. Why || did he not draw his sword and cut the hair of his head, and get down? But he saw that Gehinnom was open beneath him, and he said: It is better for me to hang by my hair and not to descend into the fire; therefore he was hanging, as it is said, "Behold, I saw Absalom hanging in an oak" (2 Sam. 18:10).
