1 Corinthians 14:9-11

NHEB(i) 9 So also you, unless you uttered by the tongue words easy to understand, how would it be known what is spoken? For you would be speaking into the air. 10 There are, it may be, so many kinds of voices in the world, and none is without meaning. 11 If then I do not know the meaning of the sound, I would be to him who speaks a foreigner, and he who speaks would be a foreigner to me.
