14:7 {3} And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped?
(3) He sets forth that which he said by a similitude, which he borrows and takes from instruments of music, which although they speak not perfectly, yet they are distinguished by their sounds, that they may be the better used.
14:7 Even things without life giving sound. Musical instruments that give forth a sound, such as a pipe or a harp, the chief musical instruments of the Greeks, must give a distinction of sounds, if one would know what is played.
14:7 How shall it be known what is piped or harped - What music can be made, or what end answered?
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.
