The Sick Lion

A LION, unable from old age and infirmities to provide himself with
food by force, resolved to do so by artifice. He returned to his den,
and lying down there, pretended to be sick, taking care that his
sickness should be publicly known. The beasts expressed their sorrow,
and came one by one to his den, where the Lion devoured them. After
many of the beasts had thus disappeared, the Fox discovered the trick
and presenting himself to the Lion, stood on the outside of the cave,
at a respectful distance, and asked him how he was. “I am very
middling,” replied the Lion, “but why do you stand without? Pray enter
within to talk with me.” “No, thank you,” said the Fox. “I notice that
there are many prints of feet entering your cave, but I see no trace of
any returning.”

He is wise who is warned by the misfortunes of others.
