1 Corinthians 14:9-11 So also ye, unless ye give understandable speech by the tongue, how will that which is spoken be known? For ye will be talking into the air.

ACV⁽ⁱ⁾ ⁹ So also ye, unless ye give understandable speech by the tongue, how will that which is spoken be known? For ye will be talking into the air. ¹⁰ Since there are perhaps, so many kinds of voices in the world, and none of them is without significance. ¹¹ If therefore I know not the force of the voice, I will be a foreigner to him who speaks, and he who speaks will be a foreigner to me.
