2CH 34:12

12 And the men did the melachah [(work)] be'emunah [(faithfully, with integrity)]; and the mufkadim [(overseers)] of them were Yachat and Ovadyahu, the Levi'im, of the Bnei Merari; and Zecharyah and Meshullam, of the Bnei Kehati, to give oversight; and other of the Levi'im, all that were meiven [(expert)] in musical instruments.
