4 Whoever speaks in tongues edifies himself. But whoever prophesies edifies the Church.
5 Now I want you all to speak in tongues, but more so to prophesy. For he who prophesies is greater than he who speaks in tongues, unless perhaps he interprets, so that the Church may receive edification.
6 But now, brothers, if I were to come to you speaking in tongues, how would it benefit you, unless instead I speak to you in revelation, or in knowledge, or in prophecy, or in doctrine?
7 Even those things that are without a soul can make sounds, whether it is a wind or a stringed instrument. But unless they present a distinction within the sounds, how will it be known which is from the pipe and which is from the string?
8 For example, if the trumpet made an uncertain sound, who would prepare himself for battle?
9 So it is with you also, for unless you utter with the tongue in plain speech, how will it be known what is said? For then you would be speaking into the air.
10 Consider that there are so many different kinds of languages in this world, and yet none is without a voice.
