Rabbi Sabbathai Eisenstadt

He was rabbi in Biala, Lithuania, later in Szerszow [79/3]. In 1765, he approved Meorei A"Sh. In the same work, p. 86a, we find two explanations by him. Sabbathai lived to an old age, as we can see from his approbation dated Sunday, 7 Adar II [5]537 / [16 March] 1777 for the work Ateret Joseph by Joseph b. Dov Beer of Liskov, Zolkiew 1788, where he is called yashish ('old man') in the heading [c].

[c] His grandson Benjamin [OR 3667] was dayan in Rosinai [sp?] and died on 1 Tammuz 5607 / 15 June 1847.
