17 for thou, indeed, dost give thanks well, but the other is not built up!
18 I give thanks to my God--more than you all with tongues speaking--
19 but in an assembly I wish to speak five words through my understanding, that others also I may instruct, rather than myriads of words in an [unknown] tongue.
20 Brethren, become not children in the understanding, but in the evil be ye babes, and in the understanding become ye perfect;
21 in the law it hath been written, that, `With other tongues and with other lips I will speak to this people, and not even so will they hear Me, saith the Lord;'
22 so that the tongues are for a sign, not to the believing, but to the unbelieving; and the prophesy [is] not for the unbelieving, but for the believing,
23 If, therefore, the whole assembly may come together, to the same place, and all may speak with tongues, and there may come in unlearned or unbelievers, will they not say that ye are mad?
