1 Corinthians 14:6-9

English Standard Version

⁶ Now, brothers,^[a] if I come to you speaking in tongues, how will I benefit you unless I bring you some ^(A)revelation or knowledge or prophecy or ^(B)teaching? ⁷ If even lifeless instruments, such as the flute or the harp, do not give distinct notes, how will anyone know what is played? ⁸ And ^(C)if the bugle gives an indistinct sound, who will get ready for battle? ⁹ So with yourselves, if with your tongue you utter speech that is not intelligible, how will anyone know what is said? For you will be ^(D)speaking into the air.
