1 Corinthians 14:4

²²Therefore other languages are for a sign, not to those who believe, but to the unbelieving; but prophesying is for a sign, not to the unbelieving, but to those who believe.

²⁶What is it then, brothers? When you come together, each one of you has a psalm, has a teaching, has a revelation, has another language, or has an interpretation. Let all things be done to build each other up.

¹⁷These signs will accompany those who believe: in my name they will cast out demons; they will speak with new languages;

¹⁷For you most certainly give thanks well, but the other person is not built up. ¹⁸I thank my God, I speak with other languages more than you all. ¹⁹However, in the assembly I would rather speak five words with my understanding, that I might instruct others also, than ten thousand words in another language.

³But he who prophesies speaks to men for their edification, exhortation, and consolation.

¹²So also you, since you are zealous for spiritual gifts, seek that you may abound to the building up of the assembly.

²If I have the gift of prophecy, and know all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but don’t have love, I am nothing.

⁵Now I desire to have you all speak with other languages, but even more that you would prophesy. For he is greater who prophesies than he who speaks with other languages, unless he interprets, that the assembly may be built up.

¹⁹So then, let’s follow after things which make for peace, and things by which we may build one another up.
