2 Samuel 18:1-8 World English Bible (WEB)
18 David numbered the people who were with him, and set captains of thousands and captains of hundreds over them. 2 David sent the people out, 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. The king said to the people, “I will also surely go out with you myself.”
3 But the people said, “You shall not go out; for if we flee away, they will not care for us; neither if half of us die, will they care for us. But you are worth ten thousand of us. Therefore now it is better that you are ready to help us out of the city.”
4 The king said to them, “I will do what seems best to you.”
The king stood beside the gate, and all the people went out by hundreds and by thousands. 5 The king commanded Joab and Abishai and Ittai, saying, “Deal gently for my sake with the young man, even with Absalom.” All the people heard when the king commanded all the captains concerning Absalom.
6 So the people went out into the field against Israel; and the battle was in the forest of Ephraim. 7 The people of Israel were struck there before David’s servants, and there was a great slaughter there that day of twenty thousand men. 8 For the battle was there spread over the surface of all the country, and the forest devoured more people that day than the sword devoured.
2 Samuel 18:1-8 New International Version (NIV)
18 David mustered the men who were with him and appointed over them commanders of thousands and commanders of hundreds. 2 David sent out his troops, a third under the command of Joab, a third under Joab’s brother Abishai son of Zeruiah, and a third under Ittai the Gittite. The king told the troops, “I myself will surely march out with you.”
3 But the men said, “You must not go out; if we are forced to flee, they won’t care about us. Even if half of us die, they won’t care; but you are worth ten thousand of us.[a] It would be better now for you to give us support from the city.”
4 The king answered, “I will do whatever seems best to you.”
So the king stood beside the gate while all his men marched out in units of hundreds and of thousands. 5 The king commanded Joab, Abishai and Ittai, “Be gentle with the young man Absalom for my sake.” And all the troops heard the king giving orders concerning Absalom to each of the commanders.
6 David’s army marched out of the city to fight Israel, and the battle took place in the forest of Ephraim. 7 There Israel’s troops were routed by David’s men, and the casualties that day were great—twenty thousand men. 8 The battle spread out over the whole countryside, and the forest swallowed up more men that day than the sword.
