His Position

The Holy Tzadik and Rebbe Rav Levi Yitzhak of Berditshev was one of the foremost students of the Maggid of Mezritch, the Holy Ba'al Shem Tov's successor. Thus he is in fact only five generations removed from recieving the Torah on Mount Sinai from Hashem himself. The Rav Levi Yitzhak of Berditshev was the student of the Maggid of Mezritch, who recieved the tradition from the holy of holies a lofty soul come to down to earth from heaven: our master Rebbe Yisroel the Ba'al Shem Tov who in turn recieved the tradition from the prophet Achiya HaShiloni who was counted among those who were in the exodus from Egypt (see Rambam's introduction to the Mishna Torah), and who learned and recieved the Torah from Moshe Rabbeinu, who in turn recieved it from G-d Himself. (Toldos Kedushas Levi Munkacz 2:8)

The Chofetz Chaim Wants Help From Two Berditchev Grandchildren

One Rosh Chodesh Elul, two bochurim arrived in Radin, and requested to be accepted in the yeshivah. However, the yeshivah was already completely full, and they were not accepted due to lack of space. The bochurim prepared to return home, and before they left, they approached the Chofetz Chaim to receive a bracha.

After the Chofetz Chaim spoke with the bochurim, the Chofetz Chaim summoned his son-in-law, who ran the yeshivah, and requested that the bochurim be accepted into the yeshivah despite the lack of space. While speaking to the boys, the Chofetz Chaim had discovered that they were the grandchildren of Rav Levi Yitzchak of Berditchev. He decided that during the approaching days of Din, he wanted the merit of davening together with the grandsons of the defender of Yisrael (Shlomo Kook)
