2 Samuel 18:3-4

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].”

4Then 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.
