(3) No fewer than twenty-one trumpet blasts are sounded daily in the Temple, as each day three blasts were sounded for the opening of the gates in the morning, nine for the daily morning offering, and nine for the daily afternoon offering, totaling twenty-one. And no more than forty-eight are ever sounded on a single day. This would occur on the Friday of Sukkot, when they would sound an additional twelve blasts during the ritual of drawing the water for the water libation; nine for the additional offerings; three to signal the population to cease their work before Shabbat; and three more to mark the beginning of Shabbat. When accompanying their song with instruments, the Levites do not use fewer than two lyres and do not use more than six. When flutes are played, they do not use fewer than two flutes and do not use more than twelve. And there are twelve days during the year when the flute plays before the altar: At the time of the slaughter of the first Paschal offering, on the fourteenth of Nisan; and at the time of the slaughter of the second Paschal offering, on the fourteenth of Iyyar; and on the first festival day of Passover; and on the festival of Shavuot; and on all eight days of the festival of Sukkot. And one would not play with a copper flute; rather, one would play with a flute of reed, because its sound is more pleasant. And one would conclude the music only with a single flute, because it concludes the music nicely.
