It is a well-known quote, “the wolf in sheep’s clothing”.

Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves (Gospel of Matthew 7:15, King James Version)

Fables of Aesop also speak of wolves that are mistakenly trusted by shepherds; the moral drawn from these is that one’s basic nature eventually betrays itself.

Sheep in Wolf's Clothing

Why shroud our true malevolent selves in the cowardice of sheepskin and pretend to be a common plebeian when we can instead disguise our fears and insecurities with the aggressive face of the wolf? A girl, naked to the bones, cradles the head of a sheep. She buries her vulnerability underneath the savagery of the wolf.
