2 Samuel 18:1-5

David organized his forces. He appointed captains of thousands and captains of hundreds. Then David deployed his troops, a third under Joab, a third under Abishai son of Zeruiah, Joab’s brother, and a third under Ittai the Gittite. The king then announced, “I’m marching with you.” They said, “No, you mustn’t march with us. If we’re forced to retreat, the enemy won’t give it a second thought. And if half of us die, they won’t do so either. But you are worth ten thousand of us. It will be better for us if you stay in the city and help from there.” “If you say so,” said the king. “I’ll do what you think is best.” And so he stood beside the city gate as the whole army marched out by hundreds and by thousands. Then the king ordered Joab and Abishai and Ittai, “Deal gently for my sake with the young man Absalom.” The whole army heard what the king commanded the three captains regarding Absalom.
