2 Samuel 18:1-9

1 And David numbered the people that were with him, and set captains of thousands and captains of hundreds over them.
2 And David sent forth the people, a third part under the hand of Joab, and a third part under the hand of Abishai the son of Zeruiah, Joab's brother, and a third part under the hand of Ittai the Gittite. And the king said unto the people, I will surely go forth with you myself also.
3 But the people said, Thou shalt not go forth: for if we flee away, they will not care for us; neither if half of us die, will they care for us: but thou art worth ten thousand of us; therefore now it is better that thou be ready to succor us out of the city.
4 And the king said unto them, What seemeth you best I will do. And the king stood by the gate-side, and all the people went out by hundreds and by thousands.
5 And the king commanded Joab and Abishai and Ittai, saying, Deal gently for my sake with the young man, even with Absalom. And all the people heard when the king gave all the captains charge concerning Absalom.
6 So the people went out into the field against Israel: and the battle was in the forest of Ephraim.
7 And the people of Israel were smitten there before the servants of David, and there was a great slaughter there that day of twenty thousand men.
8 For the battle was there spread over the face of all the country; and the forest devoured more people that day than the sword devoured.
9 And Absalom chanced to meet the servants of David. And Absalom was riding upon his 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 heaven and earth; and the mule that was under him went on.
