The organization responsible for the posters is Lehava (a word meaning flame and a Hebrew acronym for "Preventing Assimilation in the Holy Land" ), whose name has emerged repeatedly in recent months. The organization is responsible for disseminating the so-called rabbis' wives letter, which called on Jewish girls not to date Arabs. It helped organize a demonstration in Bat Yam in which people held signs stating "Jewish girls for the Jewish people." And it operates an initiative providing kosher seals of approval for businesses that don't employ Arabs.

So what exactly is this organization? An investigation by Haaretz Magazine reveals that, although Lehava is not registered as a non-profit organization or as another type of statutory body, its leading and prominent activists are connected to an NPO called Hemla (Mercy ), which receives funding from the state.
