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)
