5. Now I wish you all spoke with tongues, but rather that you might prophesy, for he who is prophesying is greater than he who is speaking with tongues, unless he interprets, so that the assembly might receive upbuilding.
6. But now, brothers, if I come to you speaking with tongues, what shall I profit you unless I speak to you, either by revelation, or by knowledge, or by prophesying, or by teaching?
7. Nevertheless, lifeless instruments making a sound, whether flute or harp, if they do not make a distinction in the sound, how shall it be known what is played on the flute or on the harp?
8. For indeed, if the trumpet makes an indistinct sound, who shall prepare himself for battle?
9. So also you, if you do not give speech by the tongue that is clear, how shall it be known what is spoken? For you shall be speaking into the air.
