Par Echad is a 19th-century commentary on Pirkei DeRabbi Eliezer, a midrash dated to the eighth century that retells and expands upon biblical stories. Written by Rabbi Hayyim Palache, a leading Turkish rabbinic figure, the work offers brief commentary that compares the text of Pirkei DeRabbi Eliezer with parallel texts found in other midrashic works, points the reader to relevant earlier commentaries and legal works, and provides brief analysis of the midrashic text. The book’s title is a scrambled acronym of the Hebrew phrase “Pirkei Rabbi Eliezer Divrot (the words of) Hayyim.”
