7 Even in the case of lifeless things that make sounds, such as the pipe or harp, how will anyone know what tune is being played unless there is a distinction in the notes?
7 If even lifeless instruments, such as the flute or the harp, do not give distinct notes, how will anyone know what is played?
7 If musical instruments - flutes, say, or harps - aren't played so that each note is distinct and in tune, how will anyone be able to catch the melody and enjoy the music?
7 Even things without life, whether flute or harp, when they make a sound, unless they make a distinction in the sounds, how will it be known what is piped or played?
7 Even lifeless instruments like the flute or the harp must play the notes clearly, or no one will recognize the melody.
Matthew Henry's Commentary on 1 Corinthians 14:7
Commentary on 1 Corinthians 14:6-14
(Read 1 Corinthians 14:6-14)
Even an apostle could not edify, unless he spoke so as to be understood by his hearers. To speak words that have no meaning to those who hear them, is but speaking into the air. That cannot answer the end of speaking, which has no meaning; in this case, speaker and hearers are barbarians to each other. All religious services should be so performed in Christian assemblies, that all may join in, and profit by them. Language plain and easy to be understood, is the most proper for public worship, and other religious exercises. Every true follower of Christ will rather desire to do good to others, than to get a name for learning or fine speaking.
