I Crônicas 9:33

33 Those who were musicians, heads of Levite families, stayed in the rooms of the temple and were exempt from other duties because they were responsible for the work day and night.

33 Os cantores, chefes das famílias levitas, permaneciam nas salas do templo e estavam isentos de outros deveres, pois dia e noite se dedicavam ao seu próprio ministério.
