Yeḥiel Mikhel ben Avraham ha-Leṿi Epshṭain

Yehiel Michel ben Avraham Epstein Ashkenazi , also known as Jeḥiel Michel Segal Epstein was a Sabbatean writer and ethicist who lived in the seventeenth century. He refers to himself as an Ashkenazic Jew. He was the son-in-law of a certain rabbinical judge named "Yom-Tov Oppenheim".

In 1693, Yehiel Michel published Ḳiẓẓur Shnei Luḥot haBrit , also known as Kitzur Shelah , written after the style of Isaiah Horowitz's Shnei Luḥot haBrit (1648). A second edition, with numerous additions, and containing extracts from current ethical works, was published three years later (Fürth, 1696) and a third edition with even more material was published in Amsterdam (1723). Jacob Emden publicized the Sabbatean nature of the work in Torat Kinna'ot (1752) and explicit references to Zevi were excised from subsequent editions.
