Hope is a virtue that very strongly befits the office of a knight, for through hope knights remember God in battle, in their trials and tribulations, and through the hope that they have in Him they receive succour and aid from God who triumphs in battle because of the hope and trust that the knights have in His power rather than in their strength or weapons. With hope the knight's courage is fortified and revitalized, and hope allows them to endure travails and makes them venture into the perils into which they place themselves, and hope makes them endure hunger and thirst in the castles and cities that they defend when they are besieged. And if there were no hope the knight would not have the wherewithal to fulfil the office of knighthood.
