Rabbi Tzvi Elimelech of Dinov was on his way to visit his Rebbe, the Chozeh (Seer) of Lublin. During the journey he began to wonder from which of the Twelve Tribes he descended.
"Why is it," he thought to himself, "that as soon as Chanukah nears, I always experience a special spiritual delight? I cannot be descended from the Hasmoneans, for I am not of the priestly family. So where does this special feeling come from?"
Rabbi Tzvi Elimelech decided that when he was in Lublin, he would ask his Rebbe. Upon arriving at the Chozeh's court, before he even managed to say a word, the Chozeh said: "You are descended from the Tribe of Yissachar. As to why you experience what you do on Chanukah, it is because in the time of the Holy Temple you were a member of the Rabbinical Court of the Hasmoneans" for the Tribe of Yissachar traditionally supplied the scholars who manned the Rabbinal Court in Temple times.
That is why Reb Tzvi Elemelech entitled his learned book on the festivals, Bnei Yissachar - the Sons of Yissachar.
