Two nights they slept on the way, but on the third day, so worn was St. Francis with fatigue and illness, that his companions were fain to beg a poor peasant to lend them his ass.  As they proceeded on their journey the peasant, walking behind the ass, said to St. Francis, "Tell me now, art thou Brother Francis of Assisi?" and when St. Francis said he was, the peasant rejoined, "Look to it, then, that thou strive to be as good as folk take thee to be, so that those who have faith in thee be not disappointed in what they expect to find in thee."  And instantly St. Francis got down from the ass, and, kneeling on the ground, kissed the peasant's feet, and thanked him for his brotherly admonition.
