9. Ra'aya Meheimna (the Faithful Shepherd). "From thirty years old and upward to fifty years old, everyone that came to do the service of the ministry, and the service of carrying in the Tent of Meeting" (Bemidbar 4:47). This commandment IS THAT the Levites should sing in the Temple. Although this was already explained before, we need to add something new, for it is the priest who sacrifices the offering and he is THE ANGEL Michael, WHO IS CHESED, CHESED BEING THE PRIEST. The Levite is Gabriel, WHO IS GVURAH, AND GVURAH IS CALLED LEVITE. And he should play music.
