1 Corinthians 14:7-9

And even Greek, ομως, in like manner, (the word, it seems, being here used for ομοιως, as it sometimes is by the poets, see Beza and Macknight,) things without life Inanimate things; whether pipe or harp Or any other instrument of music; except they give a distinction Greek, διαστολην φθογγοις, a difference to the notes. “Among musicians, the former word signifies the measured distance between sounds, according to certain proportions, from which the melody of a tune results.” And Raphelius has shown that the latter word, as distinguished from φωνη, voice, signifies a musical sound, a note in music. How shall it be known what is piped or harped What music can be made, or what end answered? For Or, moreover; in war, if Instead of sounding those notes whose meaning is understood by the soldiers, the trumpet give an uncertain sound, who shall prepare himself to the battle How could soldiers know when to advance or when to retreat, unless the trumpet sounds were adjusted, and constantly adhered to? So likewise In your religious assemblies; except ye utter words easy to be understood Significant words, to which the ears of your auditory are accustomed; how shall it be known what is spoken What is intended to be signified by your expressions? For ye shall speak into the air (A proverbial expression,) you will utterly lose your labour.
