1 Corinthians 14:9-11 So also you, if you do not give a clear word through the language, how will it be known what is being said? For you will be speaking into the air.

MKJV⁽ⁱ⁾ ⁹ So also you, if you do not give a clear word through the language, how will it be known what is being said? For you will be speaking into the air. ¹⁰ So it may be many kinds of sounds are in the world, and not one is without a distinct sound. ¹¹ Therefore if I do not know the power of the sound, I will be a foreigner to him speaking, and he speaking will be a foreigner to me.
