Art thou not aware of those elders of the children of Israel, after the time of Moses, how they said unto a prophet of theirs, "Raise up a king for us, [and] we shall fight in God's cause"? Said he: "Would you, perchance, refrain from fighting if fighting is ordained for you?" They answered: "And why should we not fight in God's cause when we and our children have been driven from our homelands?" Yet, when fighting was ordained for them, they did turn back, save for a few of them; but God had full knowledge of the evildoers.
