14 Follow after charity, and desire spiritual gifts, but rather that ye may prophesy. 2 For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries. 3 But he that prophesieth speaketh unto men to edification, and exhortation, and comfort. 4 He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church. 5 I would that ye all spake with tongues but rather that ye prophesied: for greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.
