1 Corinthians 14:18-23

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

20Brothers, ado not be children in your thinking. bBe infants in evil, but in your thinking be cmature. 21 dIn the Law it is written, eBy 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.” 22Thus tongues are a sign not for believers but for unbelievers, while prophecy is a sign
Greek lacks  a sign
not for unbelievers but for believers.
23If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, gwill they not say that you are out of your minds?
