Three Hundred Æsop's Fables/The Wild Boar and the Fox
THE WILD BOAR AND THE FOX.
A Wild Boar stood under a tree, and rubbed his tusks against the trunk. A Fox passing by, asked him why he thus sharpened his teeth when there was no danger threatening from either huntsman or hound. He replied, "I do it advisedly; for it would never do to have to sharpen my weapons just at the time I ought to be using them."
To be well prepared for war is the best guarantee of peace.
