1 Corinthians 14:4–5
4 The one who speaks in a tongue builds up himself, but the one who prophesies builds up the church. 5 Now I want you all to speak in tongues, but xeven more to prophesy. The one who prophesies is greater than the one who speaks in tongues, unless someone interprets, so that the church may be built up.
1 Corinthians 14:39
39 So, my brothers, dearnestly desire to prophesy, and do not forbid speaking in tongues.
