Ayin hara
The Hebrew name for the evil eye, the harm that praise or envy is believed to bring, and the words said to ward it off.
Also: ayin ha-ra, ayin hora, kinehora, kein ayin hara, evil eye
Ayin hara (עין הרע), the evil eye, appears in the Talmud, which discusses harm from a hostile glance. Rabbinic writers also advise modesty about good fortune. In Yiddish-speaking communities the phrase kinehora, from keyn ayin hore, is added after a compliment or a good report as a precaution, often with a spit sound. Jewish customs against it include a red thread, a hamsa, and not counting people directly. In Sephardic and Mizrahi communities, amulets and blessings are widely used. The belief is shared by many peoples, who call it nazar, mal de ojo or malocchio. Some rabbis treat it as a real concern, others as a metaphor for envy and the need for discretion.
