Levi Yitzchok of Berditchev (1740-1809), also known as the Berdichever was a rabbi and Hasidic leader. He was one of the main disciples of the Maggid of Mezritch. Reb Levi Yitzchok was known as the "defense attorney" for the Jewish people, because it was believed that he could intercede on their behalf before God. Known for his compassion for every Jew, he was therefore one of the most beloved leaders of Eastern European Jewry. He authored the Hasidic classic Kedushas Levi, which is a commentary on many Jewish religious books and laws, and is arranged according to the weekly Torah portion.
