The Birds, the Beasts, and the Bat

by Aesop

THE BIRDS waged war with the Beasts, and each party were by turns the conquerors. A Bat, fearing the uncertain issues of the fight, always betook himself to the side which was the strongest. When peace was proclaimed, his deceitful conduct was apparent to both combatants; he was driven forth from the light of day, and henceforth concealed himself in dark hiding-places, flying always alone and at night.

Moral:
Those who practice deceit must expect to be shunned.
