Abstemius's Fables (Sir Roger L'Estrange)
271. (Abstemius 17) An Eele and a Snake.
You and I are so alike, says the Eele to the Snake, that methinks we should be somewhat a-kin; and yet they that persecute me, are afraid of you. What should be the reason of this? Oh (says the Snake) because no body does me an Injury but I make him smart for't.
In all Controversies they come off best that keep their Adversaries in fear of a Revenge.
