A wolf in sheep's clothing
Meaning
Someone who appears harmless or friendly but is actually dangerous or malicious.
Origin
The vivid image of a predator disguised as its prey originates from the New Testament, specifically Matthew 7:15. Here, Jesus issues a dire warning to his followers: 'Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves.' This parable powerfully cautions against those who feign innocence or benevolence to conceal their true, destructive intentions. The imagery perfectly captures the deceptive nature of individuals who hide their malice beneath a facade of harmlessness, making the phrase an enduring symbol of duplicity that has resonated through centuries.
