The Platform: Uses

A minimum of twelve Levites stood on the platform each day, and the number of singers in the choir could be expanded without limit. Certain Israelites of unqestionable descent were also entitled to ascend the platform and accompany the Levites with instruments. On the floor near the platform stood the "Levite Trainees" - young Levites whose voices were so sweet that they "aroused the jealousy" of the older Levites. (Source: Arachin 13).
