2For 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.
3But he that prophesieth speaketh unto men to edification, and exhortation, and comfort.
4He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church.
5I 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.
6Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine?
7And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped?
8For if the trumpet give an uncertain sound, who shall prepare himself to the battle?
