(called also BEN-JACOB), a Jewish theologian of some note, flourished in the beginning of the 16th century as rabbi of the Jews of Salonica in Thessalonica. He wrote a number of works in the department of dogmatic and Biblical theology, among which special mention is due to his דרשׁ משׁה , a homiletical Commentary on the Pentateuch, accompanied by several occasional homilies (Ven. 1603, folio): — תמיד עולה, or Disquisitions on the Books of the Law, partly exegetical and partly philosophical (Ven. 1526, 1601, fol.).
