9. So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye will speak into the air.
10. There are, it may be, so many kinds of voices in the world, and none of them is without signification.
11. Therefore, if I know not the meaning of the voice, I shall be to him that speaketh a barbarian, and he that speaketh will be a barbarian to me.
12. Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church.
