SHY: “רש”י במדבר כא, כא:
שמשה הוא ישראל וישראל הם משה, לומר לך שנשיא הדור הוא ככל הדור, כי הנשיא הוא הכל”
Did you read what I orignally wrote? I specifically said that the term has not been applied to anyone in many hundreds of years. Quoting Rashi referring to Moshe Rabbeinu is totally irrelevant.
