1 Corinthians 14:7
Nestle 1904 Greek New Testament · Berean Standard Bible
ὅμως τὰ ἄψυχα φωνὴν διδόντα εἴτε αὐλὸς εἴτε κιθάρα ἐὰν διαστολὴν τοῖς φθόγγοις μὴ δῷ πῶς γνωσθήσεται τὸ αὐλούμενον ἢ τὸ κιθαριζόμενον
Even in the case of lifeless instruments, such as the flute or harp, how will anyone recognize the tune they are playing unless the notes are distinct?
