7yet the things without life giving sound -- whether pipe or harp -- if a difference in the sounds they may not give, how shall be known that which is piped or that which is harped?
8for if also an uncertain sound a trumpet may give, who shall prepare himself for battle?
9so also ye, if through the tongue, speech easily understood ye may not give -- how shall that which is spoken be known? for ye shall be speaking to air.
10There are, it may be, so many kinds of voices in the world, and none of them is unmeaning,
11if, then, I do not know the power of the voice, I shall be to him who is speaking a foreigner, and he who is speaking, is to me a foreigner;
12so also ye, since ye are earnestly desirous of spiritual gifts, for the building up of the assembly seek that ye may abound;
13wherefore he who is speaking in an [unknown] tongue -- let him pray that he may interpret;
