A wolf in disguise
Meaning
A person who appears friendly or harmless but is secretly dangerous, malicious, or has harmful intentions.
Origin
The potent image of a predatory wolf hiding among innocent sheep has roots stretching back to ancient fables, but it was powerfully solidified into a core warning in the New Testament. In Matthew 7:15, Jesus cautions his followers, "Beware of false prophets, which come to you in sheep's clothing, but inwardly they are ravening wolves." This vivid metaphor paints a picture of profound deceit, where an outward appearance of gentleness or piety conceals a malevolent, destructive intent. While the direct biblical quote uses "sheep's clothing," the phrase "a wolf in disguise" captures the same timeless admonition, reminding us to look beyond the surface, as danger often lurks beneath a veneer of harmlessness or even friendliness. It's a principle as relevant today as it was in ancient Judea, warning against those who would exploit trust.
Examples
