6 Now, brothers,¹ if I come to you speaking in tongues, how will I benefit you unless I bring you some ^yrevelation or knowledge or prophecy or ^zteaching?

18 I thank God that I speak in tongues more than all of you.

22 Thus tongues are a sign not for believers but for unbelievers, while prophecy is a sign¹ not for unbelievers but for believers.

23 If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, ^mwill they not say that you are out of your minds?

29 Let two or three prophets speak, and let the others ^vweigh what is said.
