2 Chronicles 34:12-13

34:12 The men worked faithfully. Their supervisors were Jahath and Obadiah (Levites descended from Merari), as well as Zechariah and Meshullam (descendants of Kohath). The Levites, all of whom were skilled musicians, 34:13 supervised the laborers and all the foremen on their various jobs. Some of the Levites were scribes, officials, and guards.
