I Corinthians 14:2-5

For he who speaks in a tongue does not speak to men but to God, for no one understands him; however, in the spirit he speaks mysteries. But he who prophesies speaks edification and exhortation and comfort to men. He who speaks in a tongue edifies himself, but he who prophesies edifies the church. I wish you all spoke with tongues, but even more that you prophesied; for he who prophesies is greater than he who speaks with tongues, unless indeed he interprets, that the church may receive edification.
