BERTINORO, OBADIAH, Jewish commentator of the Mishnah, died in Jerusalem about 1500. Bertinoro much improved the status of the Jews in the Holy Land; before his migration thither the Jews of Palestine were in a miserable condition of poverty and persecution. His commentary on the Mishnah is the most useful of all helps to the understanding of that work. It is printed in most Hebrew editions of the Mishnah. Surenhusius, in his Latin edition of the last-named code (Amsterdam 1698–1703), translated Bertinoro’s commentary.
