The Lion and the Four Bulls
Four Bulls, which had entered into a very strict friendship, kept always near one another, and fed together. The Lion often saw them, and as often wished to make one of them his prey; but though he could easily have subdued any of them singly, yet he was afraid to attack the whole when together, knowing they would have been too hard for him; and, therefore, contented himself for the present with keeping at a distance. At last, perceiving no attempt was to be made upon them as long as their combination lasted, he took occasion, by whispers and hints, to foment jealousies and raise divisions among them.
This stratagem succeeded so well, that the Bulls grew cold and reserved towards one another, which soon after ripened into a downright hatred and aversion, and, at last, ended in a total separation. The Lion had now obtained his ends; and, as impossible as it was for him to hurt them while they were united, he found no difficulty, now they were parted, to seize and devour every Bull of them, one after another.
Union is strength. Jealousy and envy, especially when fomented by whisperers, will destroy gradually the ties that make us safe against enemies.
