With three crowns was Israel crowned – with the crown of Torah, the crown of Priesthood, and the crown of Kingship. The crown of Priesthood was bestowed on Aaron and his descendants. The crown of Kingship was conferred on David and his successors. But the crown of Torah is for all Israel. Whoever wishes, let them come and take it. Do not suppose that the other two crowns are greater than that of Torah…. The crown of Torah is greater than the other two crowns.
