EPHRAIM BEN JACOB HA-KOHEN:
Lithuanian Talmudist; born at Wilna 1616; died June 3, 1678, at Ofen, Hungary. Driven by the Chmielnicki persecutions from his native city, where he was dayyan, he went to Moravia. He filled the office of rabbi, first at Trebitsch and then at Ofen.
Ephraim's works include: "Sha'ar Efrayim," responsa arranged according to the order of the Shulḥan 'Aruk (Sulzbach, 1688); and "Maḥaneh Efrayim," notes to the Pentateuch, which he left in manuscript.
