Join Rabbi Dr. Jon Kelsen for Mishnah Temurah every Sunday! This course is a presentation of the Rifka Rosenwein Z”L Mishnah Division. And join Drisha’s Mishnah Yomit community! Working with the most standard daily mishnah study schedule, you will join a group of committed learners who dedicate time each day for the study of 1–2 mishnayot. Over a period of weeks and months of regular study, you will complete Tractates and even entire Orders of Mishnah.

Tractate Temurah mainly discusses the prohibition against substituting a non-consecrated animal for a consecrated animal, and the sacred status that both animals receive if this prohibition is violated.

To anchor and support your individual learning, Drisha’s Mishnah Yomit program includes a weekly Mishnah Yomit b’Iyun (in-depth) shiur. In this shiur, you will have the opportunity to review portions of the past week’s material and go deep into select elements of the text (e.g., core concepts discussed; how the mishnayot interpret and interact with the biblical background; the literary structure and reception history of the unit) — all within the context of a collaborative community of fellow learners.
