Ohr LaYesharim is a 21st-century Hebrew commentary on certain tractates in the Jerusalem Talmud. It consists of two parts: clear and accessible in-line explanations of each phrase in the talmudic text, and more detailed elucidations that summarize the structure and conclusion of talmudic passages, explain the function of key talmudic phrases, compare select texts to their parallels in rabbinic literature, and expand upon topics addressed in the Talmud.
