While the cunning of the serpent wrought its own undoing, the cunning of the fox stood him in good stead in many an embarrassing situation. After Adam had committed the sin of disobedience, God delivered the whole of the animal world into the power of the Angel of Death, and He ordered him to cast one pair of each kind into the water. He and leviathan together thus have dominion over all that has life.
When the Angel of Death was in the act of executing the Divine command upon the fox, he began to weep bitterly. The Angel of Death asked him the reason of his tears, and the fox replied that he was mourning the sad fate of his friend. At the same time he pointed to the figure of a fox in the sea, which was nothing but his own reflection. The Angel of Death, persuaded that a representative of the fox family had been cast into the water, let him go free.
The fox told his trick to the cat, and she in turn played it on the Angel of Death. So it happened that neither cats nor foxes are represented in the water, while all other animals are.
