There is a story of a king who was travelling and hunting in the woods, and the king was hungry and stopped at the house of a peasant who treated him very kindly. When the king was leaving this peasant, he was so touched with his kindness that without telling him he was a king he said to him, "Take this ring, and if ever you are in trouble, come to me in the city and I will see what I can do for you." After a time there was a famine and the peasant was in great trouble; his wife and child were dying, and he set out to see this man.
