G2789–κιθαρίζω–kitharizō

Even things without life, giving a voice, whether pipe or harp, if they didn't give a distinction in the sounds, how would it be known what is piped or harped?

κιθαριζόμενον; kitharizomenon “is being harped?”

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.

κιθαριζόντων kitharizontōn “harping”
