1 Corinthians 14:7-9

Legacy Standard Bible

⁷ Yet even lifeless things, either flute or harp, in producing a sound, if they do not produce a distinction in the tones, how will it be known what is played on the flute or on the harp? ⁸ For if ^(A)the trumpet produces an indistinct sound, who will prepare himself for battle? ⁹ So also you, unless you utter by the tongue a word that is clear, how will it be known what is spoken? For you will be ^(B)speaking into the air.
