1 Corinthians 14:7-9

Disciples’ Literal New Testament

⁷ Likewise the lifeless things giving a sound— whether a flute or harp— if it does not give a distinction in the tones, how will the thing being fluted or the thing being harped be known? ⁸ For indeed, if a trumpet gives an uncertain sound, who will prepare himself for battle? ⁹ So also you with the tongue— if you do not give a clear word, how will the thing being spoken be known? For you will be speaking into the air!
