a Jewish writer, son of Jacob, was born in 1670, and was a rabbi at Jerusalem, but at length settled in Amsterdam, where he supported himself by instructing young men-in the Talmud. In the excitement which ensued against him and Ashkenazi, on account of the ban which they had pronounced against the impostor Chajon (q.v.), he was obliged to leave Holland, and went to Altona, and thence to Sidon, where he died, about 1744. He wrote, מסעי פרשת אלה, a topographical description of Jerusalem and the holy sepulchres (Altona, 1738): — שפת אמת, on the migrations of the Jews to Palestine (Amst. 1707): — שבר פושעים, against Chajon's heresy and his adherents (Lond. 1714).
