3 But he that prophesieth, speaketh to men unto edification, and exhortation, and comfort.
4 He that speaketh in a tongue, edifieth himself: but he that prophesieth, edifieth the church.
5 And I would have you all to speak with tongues, but rather to prophesy. For greater is he that prophesieth, than he that speaketh with tongues: unless perhaps he interpret, that the church may receive edification.
6 But now, brethren, if I come to you speaking with tongues, what shall I profit you, unless I speak to you either in revelation, or in knowledge, or in prophecy, or in doctrine?
7 Even things without life that give sound, whether pipe or harp, except they give a distinction of sounds, how shall it be known what is piped or harped?
8 For if the trumpet give an uncertain sound, who shall prepare himself to the battle?
9 So likewise you, except you utter by the tongue plain speech, how shall it be known what is said? For you shall be speaking into the air.
