1 Corinthians 14:9-11 GOD’S WORD Translation (GW)
9 In the same way, if you don’t speak in a way that can be understood, how will anyone know what you’re saying? You will be talking into thin air.
10 No matter how many different languages there are in the world, not one of them is without meaning. 11 If I don’t know what a language means, I will be a foreigner to the person who speaks it and that person will be a foreigner to me.
