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 D`estes forão tambem os cantores, cabeças dos pais entre os Levitas nas camaras, exemptos de serviço: porque dia e noite estava a seu cargo, occupar se naquella obra.
