Tochachath Megulah Vehatzad Nachash [anti-Sabbatian]. Two parts in one.

A two-pronged attack that sought to censure Nehemiah Hayon, perhaps the most militant champion of Sabbatian revisionism. Ergas’ polemic against Hayon contained both kabbalistic refutations of the legitimacy of Sabbatian mystical belief and harsh invective against Hayon personally. The second part of the volume [“To Ensnare a Serpent”] is a retaliation to Hayon’s attack upon the Chacham Zvi (entitled Hatzad Zvi [“To Ensnare a Deer”]. On Ergas’ role in this controversy see E. Carlebach, The Pursuit of Heresy (1990) pp.137-143; and B. Naor, Post Sabbatian Sabatianism (1999) pp.145-49.
