2 Samuel 18:1-5

David numbered the men who were with him and set over them commanders of thousands and commanders of hundreds. Then David sent the army out, a third under the command of Joab, a third under Abishai the son of Zeruiah, Joab’s brother, and a third under the command of Ittai the Gittite. And the king said to the men, “I myself will certainly go out [to fight] with you.” But the men said, “You should not go out [to battle with us]. For if in fact we retreat, they will not care about us; even if half of us die, they will not care about us. But you are worth ten thousand of us. So now it is better that you be ready to help us from the city [of Mahanaim].” Then the king said to them, “I will do whatever seems best to you.” So the king stood beside the gate [of Mahanaim], and all the army went out in groups of hundreds and of thousands. The king commanded Joab and Abishai and Ittai, saying, “Deal gently with the young man Absalom for my sake.” And all the men heard when the king gave orders to all the commanders about Absalom.
