⁶ But now, brothers and sisters, if I come to you speaking in tongues, how will I benefit you unless I speak to you either by way of ^(A)revelation, or of ^(B)knowledge, or of ^(C)prophecy, or of ^(D)teaching?

⁹ So you too, unless you produce intelligible speech by the tongue, how will it be known what is spoken? For you will just be ^(A)talking to the air.

¹¹ So if I do not know the meaning of the language, I will be ^(A)unintelligible to the one who speaks, and the one who speaks will be unintelligible ^[a]to me.

¹² So you too, since you are eager to possess ^[a]spiritual gifts, strive to excel for the ^(A)edification of the church.

²⁴ But if all ^(A)prophesy, and an unbeliever or an ^[a]outsider enters, he is ^(B)convicted by all, he is called to account by all;

²⁸ but if there is no interpreter, he is to keep silent in church; and have him speak to himself and to God.
