1 Corinthians 14:6, 26

Now, brothers and sisters, if I come to you and speak in tongues, what good will I be to you, unless I bring you some revelation or knowledge or prophecy or word of instruction?

What then shall we say, brothers and sisters? When you come together, each of you has a hymn, or a word of instruction, a revelation, a tongue or an interpretation. Everything must be done so that the church may be built up.
