2 For ^wone who speaks in a tongue speaks not to men but to God; for no one understands him, but he utters mysteries in the Spirit.

18 I thank God that I speak in tongues more than all of you. 19 Nevertheless, in church I would rather speak five words with my mind in order to instruct others, than ten thousand words in a tongue.

20 Brothers, ^hdo not be children in your thinking. ⁱBe infants in evil, but in your thinking be ^jmature. 21 ^kIn the Law it is written, ^l“By people of strange tongues and by the lips of foreigners will I speak to this people, and even then they will not listen to me, says the Lord.” 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?

27 If any speak in ^sa tongue, let there be only two or at most three, and each in turn, and let someone interpret.
