Thomson(i)
6 For instance, should I, brethren, come to you, speaking with tongues, what shall I profit you, unless I explain to you what I say, be it either a revelation, or science, or a prophecy, or a doctrine.
7 In like manner with regard to inanimate things which give a sound, whether pipe or kithara, unless they produce distinct notes, how can it be known what that is, which is played on the pipe or kithara.
8 For if even a trumpet give an undistinguishable sound who will prepare himself for battle?
9 So also with regard to you, unless you utter with the tongue a discourse of a clear signification, how can that which is spoken be known? You will be indeed talking to the air.
