1 Corinthians 14:4; 1 Corinthians 14:22; 1 Corinthians 14:25; 1 Corinthians 14:30-31

4 He who speaks in a tongue edifies himself, but he who prophesies edifies the church.
22 Tongues, then, are a sign, not for believers but for unbelievers; prophecy, however, is for believers, not for unbelievers.
25 and the secrets of his heart will be laid bare. So he will fall down and worship God, exclaiming, "God is really among you!"
30 And if a revelation comes to someone who is sitting down, the first speaker should stop. 31 For you can all prophesy in turn so that everyone may be instructed and encouraged.
