“His tongue is like a poisoned arrow… with his mouth, he speaks cordially… but in his heart, he lays a deadly trap.” Yirmiyahu 9:7
Lashon Hara kills.
Not metaphorically. Not approximately. The Sages were direct and unambiguous: negative speech about another person is compared to murder. Just as taking a life destroys a person physically, Lashon Hara destroys them socially, professionally, and emotionally. It kills their reputation, their relationships, their livelihood — sometimes all three at once. The Talmud calls it “character assassination” — and treats it with a severity that, at first glance, can seem exaggerated. After all, what is the harm in a few words?
That is exactly the question the prophet Yirmiyahu answers.
Why an arrow — and not a sword or a knife?
A sword requires the attacker to be physically close — face to face with the victim. The person being attacked can see it coming. They can plead for mercy. The attacker can have a change of heart and return the sword to its sheath. There is still a moment of human contact, a possibility of stopping.
An arrow is different. It is launched from a distance, from concealment, without the shooter ever having to confront the person they are harming. The victim never sees it coming. They may not even know who fired it. Lashon Hara works exactly this way. The person being spoken about is not in the room. They cannot defend themselves. The damage reaches them from a direction they never anticipated, from a source they may never identify.
Once released, the arrow cannot be recalled.
With a sword, the attacker can still stop. With an arrow, the moment it leaves the bow, it is beyond anyone’s control. No regret, no apology, no change of heart can bring it back. The damage is already in motion.
Our words are the same. The moment we say something negative about another person, we lose all control over it. We do not know who will repeat it, how it will be distorted, how far it will travel, or what it will eventually destroy. A comment made at a Shabbat table can reach a person’s workplace, their children’s school, their closest relationships — sometimes within hours. The moment of release is the point of no return.
But the arrow in Yirmiyahu’s image is not just any arrow. It is poisoned.
This is the detail the Sages found most chilling. An ordinary wound may heal with time. A poisoned arrow is different — it does not just wound, it kills. And it does so slowly, invisibly, continuing to spread damage long after the initial strike. The victim may not feel the full effect immediately. But the poison works.
This is precisely how Lashon Hara operates. A reputation does not collapse the moment the words are spoken. A marriage, a career, a friendship — these unravel gradually, through conversations we never hear, through impressions we never see form, until the full weight of it lands on the victim. Often irreversibly.
And here is the cruelest dimension of the metaphor. Yirmiyahu says the wicked person speaks cordially — with a warm tone, a friendly smile — while in his heart he lays a trap. This is the signature of Lashon Hara: it comes dressed as concern, as honesty, as friendship. “I’m only telling you this — don’t repeat it.” “I’m not saying anything bad, just the facts.” Pleasant on the outside. Poisoned on impact.
The Tora holds us to an extraordinary standard when it comes to speech — not because words are trivial, but because they are not. Speaking requires no physical effort. No weapon changes hands. And yet the damage can be permanent, the victim unsuspecting, and the arrow, once released, impossible to call back.
