Moses ben Isaiah Katz
MOSES BEN ISAIAH KATZ
MOSES BEN ISAIAH KATZ (end of 17th and early 18th centuries), Polish rabbi and homilist. Katz was a pupil of Solomon *Luria and was rabbi successively of Medzibezh, Brody, and Przemysl. He is the author of Penei Moshe (Wilhermsdorf, 1716), a commentary on the aggadic passages of 18 treatises of the Babylonian and Jerusalem Talmuds. (This work should not be confused with Penei Moshe, the standard commentary on the Jerusalem Talmud by Moses *Margoliot.) He reveals a remarkable homiletic ingenuity in his work Keren Or (Zolkiew, 1721). As the title suggests, the work is a commentary on this phrase which occurs in Exodus 34:30, 35 ("the skin of his face shone"). He gives no less than 50 different explanations of the phrase. It has been suggested that Katz may be identical with Moses b. Isaiah Wengrow, the author of Berit Matteh Moshe (Berlin, 1701), a commentary on the Passover Haggadah with novellae on the tractate Zevaḥim.
