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. 28 But if there is no one to interpret, let each of them keep silent in church and speak to himself and to God.
