2. Samuel 18:9

And his head caught hold of the oak - It has been supposed that Absalom was caught by the hair, but no such thing is intimated in the text. Probably his neck was caught in the fork of a strong bough, and he was nearly dead when Joab found him; for it is said, Sa2 18:14, he was yet alive, an expression which intimates he was nearly dead.

Absalom met the servants of David--or was overtaken. "It is necessary to be continually on one's guard against the branches of trees; and when the hair is worn in large locks floating down the back, as was the case with a young man of the party to which I belonged, any thick boughs interposing in the path might easily dislodge a rider from his seat, and catch hold of his flowing hair" [HARTLEY]. Some, however, think that the sacred historian points not so much to the hair, as to the head of Absalom, which, being caught while running between two branches, was enclosed so firmly that he could not disengage himself from the hold, nor make use of his hands. the mule that was under him went away--The Orientals, not having saddles as we do, do not sit so firmly on the beasts they ride. Absalom quitting his hold of the bridle, apparently to release himself when caught in the oak, the mule escaped.

And Absalom met the servants of David,.... When his army was routed, he was in such a fright that he knew not which way to flee, and instead of flying from David's men, he fled in the way of them; but none of them attempted to slay him, nor even to stop him, but let him pass by them, knowing David's charge concerning him: and Absalom rode upon a mule; as was common for great personages to do in those days, Sa2 13:29, and the mule went under the thick boughs of a great oak; and running full speed, Absalom could not guide him, nor stop, nor divert him from going under it: and his head caught hold of the oak; either the hair of his head was twisted and entangled in the thick boughs of the oak; or rather his head was jammed into a forked branch of the oak: and he was taken up between the heaven and the earth; hung in the air between both, as unworthy to live in either: and the mule that was under him went away; and left him hanging in the oak.

"And Absalom was lighted upon (יקּרא = יקּרה) by the servants of David, riding upon the mule; and the mule had come under the thick branches of the great terebinth, and his head fastened itself (remained hanging) on the terebinth, so that he was held (hung) between heaven and earth, as the mule under him went away." The imperfects, ויּבא, ויּחזק, and ויּתּן, are only a combination of the circumstantial clause רכב ואבשׁ. With regard to the fact itself, it is not clearly stated in the words that Absalom hung only by his hair, but simply that his hair entangled him in the thick branches, and his head was fastened in the terebinth, namely, by being jammed between the strong boughs.

Here is Absalom quite at a loss, at his wit's end first, and then at his life's end. He that began the fight, big with the expectation of triumphing over David himself, with whom, if he had had him in his power, he would not have dealt gently, is now in the greatest consternation, when he meets the servants of David, Sa2 18:9. Though they were forbidden to meddle with him, he durst not look them in the face; but, finding they were near him, he clapped spurs to his mule and made the best of his way, through thick and thin, and so rode headlong upon his own destruction. Thus he that fleeth from the fear shall fall into the pit, and he that getteth up out of the pit shall be taken in the snare, Jer 48:44. David is inclined to spare him, but divine justice passes sentence upon him as a traitor, and sees it executed - that he hang by the neck, be caught alive, be embowelled, and his body dispose of disgracefully. I. He is hanged by the neck. Riding furiously, neck or nothing, under the thick boughs of a great oak which hung low and had never been cropped, either the twisted branches, or some one forked bough of the oak, caught hold of his head, either by his neck, or, as some think, by his long hair, which had been so much his pride, and was now justly made a halter for him, and there he hung, so astonished that he could not use his hands to help himself or so entangled that his hands could not help him, but the more he struggled the more he was embarrassed. This set him up for a fair mark to the servants of David, and he had the terror and shame of seeing himself thus exposed, while he could do nothing for his own relief, neither fight nor fly. Observe concerning this, 1. That his mule went away from under him, as if glad to get clear of such a burden, and resign it to the…

18:9 Absalom, who took such pride in his hair, died because of it. He who had built “a monument to himself” (18:18) was then thrown into a pit after his death (18:17) and denied the dignity of a proper burial. These ironies highlight the difference between Absalom’s aspirations and his destiny.
