17. For thou verily givest thanks well, but the other is not edified.
18. I thank my God, I speak with tongues more than ye all;
19. yet in the congregation {Gr. ekklesia – called out ones} I would rather speak five words with my understanding, that I might teach others also, than ten thousand words in an unknown tongue.
20. Brothers, be not children in understanding, howbeit in malice be ye children; but in understanding be perfect.
21. In the law it is written, In other tongues and with other lips I will speak unto this people; and yet for all that, they will not hear me, saith the Lord.
22. Therefore, tongues are for a sign, not to those that believe, but to those that do not believe; but prophecy is not for those that do not believe, but for those who believe.
23. If, therefore, the whole congregation {Gr. ekklesia – called out ones} is come together into one place and all speak with tongues, and there come in those that are unlearned or unbelievers, will they not say that ye are mad?
