2 Samuel 18:1-3

1David numbered the men who were with him and set over them commanders of thousands and commanders of hundreds.

2Then 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.”

3But 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].”
