1. Follow after love and desire spiritual gifts, but especially that you may prophesy.
2. For he who speaks in an unknown tongue does not speak to men, but to God. For no one understands him, although in the spirit, he speaks mysteries.
3. But he who prophesies speaks to men for their edification and exhortation and comfort.
4. He who speaks in an unknown tongue edifies himself, but he who prophesies edifies the church.
5. I desire that you all speak in tongues, but even more that you prophesy. For greater is he who prophesies than he who speaks in tongues, unless he interprets, so that the church may receive edification.
6. Now, brothers, if I come to you speaking in tongues, what shall I profit you, unless I speak to you by revelation or knowledge or prophesying or doctrine?
7. Even when things without life give sound, whether flute or harp, how will it be known what is played unless they give a distinction in the sounds?
8. If the trumpet makes an uncertain sound, who will prepare himself for the battle?
9. So also you, unless with the tongue you speak words easy to understand, how will it be known what is spoken? For you shall speak into the air.
10. There are, it may be, so many kinds of languages in the world, and none of them is without significance.
11. Therefore, if I do not know the meaning of the speech, I shall be a barbarian to him who speaks, and he who speaks will be a barbarian to me.
12. So, seeing that you are zealous of spiritual gifts, seek that you may excel to the edifying of the church.
13. Let him who speaks in an unknown tongue pray that he may interpret.
14. For if I pray in an unknown tongue, my spirit prays, but my understanding is unfruitful.
15. What is it then? I will pray with the spirit, and I will pray with the understanding. I will sing with the spirit, and I will sing with the understanding.
