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.

11 but if I do not know the meaning of the language, I will be ^ca foreigner to the speaker and the speaker a foreigner to me.

13 Therefore, one who speaks in a tongue should pray that he may interpret. 14 For if I pray in a tongue, my spirit prays but my mind is unfruitful. 15 What am I to do? I will pray with my spirit, but I will pray with my mind also; ^dI will sing praise with my spirit, but I will ^esing with my mind also. 16 Otherwise, if you give thanks with your spirit, how can anyone in the position of an outsider¹ say ^f“Amen” to ^gyour thanksgiving when he does not know what you are saying? 17 For you may be giving thanks well enough, but the other person is not being built up. 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.

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?
