where did the saying wolf in sheep's clothing come from
Wolf in sheep's clothing The phrase originates in a sermon by Jesus recorded in the Christian New Testament: 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) [1]. The sermon then suggests that their true nature will be revealed by their actions (by their fruits shall ye know them, verse 16). In the centuries following, the phrase was used many times in the Latin writings of the Church Fathers[2] and later on in European vernacular literature.[3] A Latin proverb also emerged, Pelle sub agnina latitat mens saepe lupina (Under a sheepâ€™s skin often hides a wolfish mind). Although the story of a wolf disguised as a sheep has been counted as one of Aesop's Fables in modern times, there is no record of a fable with this precise theme before the Middle Ages, although there are earlier fables of Aesop in Greek sources to which the Gospel parable might allude.
