Then he helped the Rabbi and his family to flee the Iron Curtain. Thus, Rabbi Dessler escaped to Lithuania and continued his saintly life. Rabbi Dessler's accepting the young thief's repentance, later helped him to be saved from execution.

Prayer only accomplishes half.
Since Moshe prayed, only two died and two remained alive. Rabbi Yehudah claimed that one can abolish a bad decree through prayer. Prayer brings a person close to G-d. When someone prays, he is acknowledging that we really have no control over the situations that confront us, and we are completely in G-d's hands. When G-d sees this, He abolishes His decree, since the threat alone has accomplished the desired result, which was to bring the person close to Him.
