¹³ Therefore the one who speaks in a tongue must pray that he may interpret. ¹⁴ For if I pray in a tongue, my spirit prays but my mind is unproductive. ¹⁵ Therefore what should I do^[a]? I will pray with my spirit, but I will also pray with my mind. I will sing praise with my spirit, but I will also sing praise with my mind. ¹⁶ For otherwise, if you praise in your spirit, how will the one who fills the place of the outsider say the “amen” at your thanksgiving, because he does not know what you are saying? ¹⁷ For indeed you are giving thanks well, but the other person is not edified. ¹⁸ I give thanks to God that I speak with tongues more than all of you, ¹⁹ but in the church I prefer to speak five words with my mind, in order that I may instruct other people, than ten thousand words in a tongue.
