Polish rabbi of the seventeenth century; author of "Be'er Heṭeb," a commentary on Shulḥan 'Aruk, Oraḥ Ḥayyim, based upon the later casuists (Amsterdam, 1708). In the preface Isaiah asserts that he wrote a similar commentary to Shulḥan 'Aruk, Yoreh De'ah. Steinschneider ("Cat. Bodl." col. 1384) and Fürst ("Bibl. Jud." ii. 57) say that Isaiah was the grandson of David b. Samuel ha-Levi (ṬaZ). Fürst further says that Isaiah and his family were burned to death, probably accidentally, in 1723, while they were on their way to Palestine.
