Parallel
1 Corinthians 14:7
Robinson-Pierpont Byzantine Textform · Berean Standard Bible
Ὅμως τὰ ἄψυχα φωνὴν διδόντα, εἴτε αὐλός, εἴτε κιθάρα, ἐὰν διαστολὴν τοῖς φθόγγοις μὴ διδῷ, 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?
