In his derashot[ (parashah Shoftim, 4) the Ben Ish Hai writes: "פירש הרב נ"א ז"ל".Who is this rabbi נ"א? He cites this acrostic in other places too, but in anyone said the entire name of this rabbi. I don't think was Noam Elimelech. Maybe נ"א is roshei tevot of a name, or maybe is roshei tevot of a title (exemple: נגידי אבי, my nagid my father). I don't know. Can you help me please! Thanks and Kol tuv!
