What Judaism Teaches About Cursing and Swearing
Judaism's prohibition on evil speech (lashon hara) is one of the most stringent in all of religious law. The Chofetz Chaim, a foundational text on speech ethics, details dozens of prohibitions against negative speech. Profanity is included under this umbrella. The Talmud states that lashon hara kills three people: the speaker, the listener, and the subject. Even truth can be lashon hara if it's unnecessary and harmful. Casual cursing, while perhaps less severe than malicious gossip, still violates the principle that speech should be sacred and purposeful.
