'Harpists' in the Bible

I heard a sound from heaven, like the sound of many waters, and like the sound of a great thunder. The sound which I heard was like that of harpists playing on their harps.

The voice of harpists, minstrels, flute players, and trumpeters will be heard no more at all in you. No craftsman, of whatever craft, will be found any more at all in you. The sound of a mill will be heard no more at all in you.
