Tziyyun LeNefesh Chayyah

Tziyyun LeNefesh Chayah (Tzelach) is a Talmud commentary by renowned 18th-century rabbinic scholar, Yechezkel Landau, also known as the Noda BiYehudah after his responsa and as the Tzelach after his Talmud commentary. The work provides extensive analyses of talmudic topics, scanning and critiquing explanations of earlier commentators and offering novel interpretations. Landau published the first two volumes on tractates Pesachim (1783) and Berakhot (1791) in his lifetime; additional volumes were published posthumously. The work’s title is a tribute to Landau’s mother Chayah, to whom he dedicated the book.
