We [keep] no less than six inspected lambs in the Chamber of the Lambs, sufficient for the Sabbath and for the two festive days of Rosh Hashanah. And we may add any number. We [take] no less than two trumpets, and we may add any number. We [take] no less than nine harps, and we may add any number, but there is only one cymbal.

We have no fewer than twelve Levites standing on the platform, and we may add any number. A minor may not enter the Temple Court for the service except when the Levites are standing in song. And they would not join in the song with lyre and harp but by mouth, in order to add harmony to the melody. R’ Eliezer ben Yaakov says: They do not count in the number, and they do not stand on the platform, but they would stand on the ground, with their heads between the legs of the Levites, and they were called the Levites’ tormentors.
