1 Corinthians 14:2-5

For he that speaketh in a tongue speaketh not unto men, but unto God; for no man understandeth; but in the spirit he speaketh mysteries. But he that prophesieth speaketh unto men edification, and exhortation, and consolation. He that speaketh in a tongue edifieth himself; but he that prophesieth edifieth the church. Now I would have you all speak with tongues, but rather that ye should prophesy: and greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.
