a Spanish Jew and distinguished rabbi, converted to the Catholic faith, and baptized in 1506. Cardinal Ximenes employed him for fifteen years upon his celebrated Polyglot, after which he composed a Dictionary of the Chaldee and Hebrew words of the Old Testament, and other works relating to the text of the Holy Scriptures. In these labors he had some assistance from others; but he composed many other works by himself, mostly on the Hebrew tongue. He wrote also, from Spain, a letter to the Roman Jews, in Hebrew and Latin interlined, reproaching them for their obstinacy. —
