2 Samuel 18:2-9
2 David sent out the army—a third under Joab’s command, a third under the command of Abishai, Zeruiah’s son, and a third under the command of Ittai the Gittite. The king told the troops, “I will march out with you myself.”
3 But the troops replied, “No! You must not march out! If we flee, they won’t care about us. Even if half of us die, they won’t care about us. But you are worth ten thousand of us. It is much better if you support us from the city.”
4 The king said to them, “I will do whatever you think is best.” So the king stood beside the gate as all the troops marched out by hundreds and thousands. 5 The king gave orders to Joab, Abishai, and Ittai: “For my sake, protect my boy Absalom.” All the troops heard what the king ordered regarding Absalom to all the commanders.
6 So the troops marched into the field to meet the Israelites. The battle was fought in the Ephraim forest. 7 The army of Israel was defeated there by David’s soldiers. A great slaughter of twenty thousand men took place that day. 8 The battle spread out over the entire countryside, and the forest devoured more soldiers than the sword that day.
9 Absalom came upon some of David’s men. Absalom was riding on a mule, and the mule went under the tangled branches of a large oak tree. Absalom’s head got caught in the tree. He was left hanging in midair while the mule under him kept on going.
2 Samuel 18:15
15 Then ten young armor-bearers of Joab surrounded Absalom, struck him, and killed him.
2 Samuel 18:31-33
31 Then the Cushite arrived and said, “My master the king: Listen to this good news! The Lord has vindicated you this day against the power of all who rose up against you.”
32 The king said to the Cushite, “Is my boy Absalom okay?”
The Cushite answered, “May the enemies of my master the king and all who rise up against you to hurt you end up like that young man.”
33 The king trembled. He went up to the room over the gate and cried. As he went, he said, “Oh, my son Absalom! Oh, my son! My son Absalom! If only I had died instead of you! Oh, Absalom, my son! My son!”
