1 Corinthians 14:2

1 Earnestly pursue love and eagerly desire spiritual gifts, especially the gift of prophecy.

For he who speaks in a tongue does not speak to men, but to God. Indeed, no one understands him; he utters mysteries in the Spirit.

3 But he who prophesies speaks to men for their edification, encouragement, and comfort.

4 The one who speaks in a tongue edifies himself, but the one who prophesies edifies the church.

Do read the surrounding verses too, because the context often says more than a single verse.
