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.
10 There are, for example, so many kinds of tongues in this world; and none is without voice.
