Jewish Encyclopedia, jewishencyclopedia.com: "Polish convert to Christianity; born 1663 at Zolkiev. He was a learned rabbi. He traveled as a maggid in Poland and Germany, preaching in the synagogues. In Holland Margalita remained in Leyden for seven years teaching rabbinics. He thus became intimate with Trigland, through whose influence he was converted to the Reformed Church, as Margalita himself relates in his work "Oblatio Aaronis seu Tractatus de Passionibus Christi," Frankfort-on-the-Oder, 1706."
