2Samuel 18:5 And the king.(David).commanded Joab and Abishai and Ittai, saying, Deal gently for my sake with the young man, even with Absalom.(Absalom was David's son). And all the people heard when the king gave all the captains charge concerning Absalom.

2Samuel 18:6 So the people went out into the field against Israel: and the battle was in the wood of Ephraim;

2Samuel 18:7,8 Where the people of Israel were slain before the servants of David, and there was there a great slaughter that day of twenty thousand men. For the battle was there scattered over the face of all the country and the wood devoured more people that day than the sword devoured..(Barnes Notes:."The wood entangled them and was perhaps full of pits, precipices and morasses."; sometimes the woods hold many dangers, including also wild beasts, especially if one is not familiar with forests, etc.)

2Samuel 18:9,10 And Absalom met the servants of David. And Absalom rode upon a mule and the mule went under the thick boughs of a great oak and his head caught hold of the oak and he was taken up between the heaven and the Earth and the mule that was under him went away. And a certain man saw it and told Joab and said, Behold, I saw Absalom hanged in an oak.

2Samuel 18:11 And Joab said unto the man that told him, And, behold, you saw him and why did you not smite him there to the ground?.(Absalom was out to take the kingdom away from his father David; Joab was fiercely.loyal to David until David was old).and I would have given you ten shekels of silver and a girdle.

2Samuel 18:12,13 And the man said unto Joab, Though I should receive a thousand shekels of silver in mine hand, yet would I not put forth mine hand against the king's son, for in our hearing the king charged thee and Abishai and Ittai, saying, Beware that none touch the young man Absalom. Otherwise I should have wrought falsehood against mine own life, for there is no matter hid from the king and thou thyself wouldest have set thyself against me. 

2Samuel 18:14,15 Then said Joab, I may not tarry thus with thee.(I'm not going to stand here and listen to this). And he.(Joab).took three darts in his hand and thrust them through the heart of Absalom, while he was yet alive in the midst of the oak. And ten young men that bare Joab's armour compassed about and smote Absalom and slew him. 

2Samuel 18:16,17 And Joab blew the trumpet and the people returned from pursuing after Israel, for Joab held back the people. And they took Absalom and cast him into a great pit in the wood and laid a very great heap of stones upon him and all Israel fled every one to his tent.

2Samuel 18:18 Now Absalom in his lifetime had taken and reared up for himself a pillar, which is in the king's dale.(a valley), 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.

2Samuel 18:19,20 Then said Ahimaaz the son of Zadok, Let me now run and bear the king tidings, how that the Lord has avenged him of his enemies. And Joab said unto him, You shall not bear tidings this day, but you shalt bear tidings another day, but this day you shall bear no tidings, because the king's son is dead.

2Samuel 18:21-28 Then said Joab to Cushi, Go tell the king what you have seen. And Cushi bowed himself unto Joab and ran. Then said Ahimaaz the son of Zadok yet again to Joab, But howsoever, let me, I pray you, also run after Cushi. And Joab said, Wherefore wilt you run, my son, seeing that you have no tidings ready? But howsoever, said he, let me run. And he said unto him, Run. Then Ahimaaz ran by the way of the plain and overran Cushi. And David sat between the two gates and the watchman went up to the roof over the gate unto the wall and lifted up his eyes and looked and behold a man running alone. And the watchman cried and told the king. And the king said, If he be alone, there is tidings in his mouth. And he came apace and drew near. And the watchman saw another man running and the watchman called unto the porter and said, Behold another man running alone. And the king said, He also brings tidings. And the watchman said, I think the running of the foremost is like the running of Ahimaaz the son of Zadok. And the king said, He is a good man and comes with good tidings. And Ahimaaz called and said unto the king, All is well. And he fell down to the Earth upon his face before the king and said, Blessed be the Lord your God which has delivered up the men that lifted up their hand against my lord the king.

2Samuel 18:29-33 And the king said, Is the young man Absalom safe? And Ahimaaz answered, When Joab sent the king's servant and me your servant, I saw a great tumult, but I knew not what it was. And the king said unto him, Turn aside and stand here. And he turned aside and stood still. And, behold, Cushi came and said, Tidings, my lord the king, for the Lord has avenged you this day of all them that rose up against you.(which David's son Absalom had done). And the king said unto Cushi, Is the young man Absalom safe? And Cushi answered, The enemies of my lord the king and all that rise against you to do you hurt, be as that young man is. And the king was much moved and went up to the chamber over the gate and wept. And as he went, thus he said, O my son Absalom, my son, my son Absalom! Would God I had died for you, O Absalom, my son, my son!
