Concise Bible Dictionary:

The third son of David, by Maacah, daughter of Talmai, king of Geshur. He was remarkable for his beauty and his luxuriant hair (2 Sam. 14:25-2625But in all Israel there was none to be so much praised as Absalom for his beauty: from the sole of his foot even to the crown of his head there was no blemish in him. 26And when he polled his head, (for it was at every year's end that he polled it: because the hair was heavy on him, therefore he polled it:) he weighed the hair of his head at two hundred shekels after the king's weight. (2 Samuel 14:25‑26)). Because of his putting his half-brother Amnon to death he fled from his father and remained at Geshur three years. By the instigation of Joab, Absalom was recalled, but not admitted into the presence of his father until a later period. This reconciliation was effected at the expense of righteousness, and without any repentance on Absalom’s part — a total contrast to God’s ministry of reconciliation (2 Cor. 5:18-2018And all things are of God, who hath reconciled us to himself by Jesus Christ, and hath given to us the ministry of reconciliation; 19To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them; and hath committed unto us the word of reconciliation. 20Now then we are ambassadors for Christ, as though God did beseech you by us: we pray you in Christ's stead, be ye reconciled to God. (2 Corinthians 5:18‑20)). It was declared to David that his successor was not yet born (2 Sam. 7:1212And when thy days be fulfilled, and thou shalt sleep with thy fathers, I will set up thy seed after thee, which shall proceed out of thy bowels, and I will establish his kingdom. (2 Samuel 7:12)). This was told to David by Nathan the prophet, and probably became known to Absalom. Amnon being dead, and perhaps Chileab, his two elder brothers, he might naturally have thought that the throne should have descended to him, and this may have led to his treason. By artful acts of condescension he stole the hearts of the people, and then at Hebron he claimed to be king, and met with much encouragement. The rebellion was so strong that David fled from Jerusalem. Absalom entered the city and was joined by Amasa and Ahithophel. The latter advised Absalom to go in publicly to the concubines of David who were left at Jerusalem, that all hopes of a reconciliation might be abandoned — though this had been foretold as a punishment to David (2 Sam. 12:1111Thus saith the Lord, Behold, I will raise up evil against thee out of thine own house, and I will take thy wives before thine eyes, and give them unto thy neighbor, and he shall lie with thy wives in the sight of this sun. (2 Samuel 12:11)). By the advice of Hushai, the further counsel of Ahithophel of an immediate pursuit was set aside, and David had time to collect an army, and reach a place of safety. A war followed, and Absalom, in riding through a wood, was caught by his head in the branches of an oak, and was there put to death by Joab. David’s grief was extreme, but he was recalled to his duties by Joab. We read that Absalom had three sons and a daughter, 2 Samuel 14:2727And unto Absalom there were born three sons, and one daughter, whose name was Tamar: she was a woman of a fair countenance. (2 Samuel 14:27), yet that because he had no son left he raised up a pillar in the king’s dale, to keep his name in remembrance: it was called ABSALOM’S PLACE or monument (2 Sam. 18:1818Now Absalom in his lifetime had taken and reared up for himself a 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 unto this day, Absalom's place. (2 Samuel 18:18)). A building in the valley of the Kedron partly rock-hewn, is called Absalom’s tomb; but it can have nothing to do with the above pillar unless it has been much added to with comparatively modern architecture.
