⁶ Now, brothers,^[a] if I come to you speaking in tongues, how will I benefit you unless I bring you some ^(A)revelation or knowledge or prophecy or ^(B)teaching?

⁹ So with yourselves, if with your tongue you utter speech that is not intelligible, how will anyone know what is said? For you will be ^(A)speaking into the air.

¹¹ but if I do not know the meaning of the language, I will be ^(A)a foreigner to the speaker and the speaker a foreigner to me. ¹² So with yourselves, since you are eager for manifestations of the Spirit, strive to excel in building up the church.

¹⁵ What am I to do? I will pray with my spirit, but I will pray with my mind also; ^(A)I will sing praise with my spirit, but I will ^(B)sing with my mind also. ¹⁶ Otherwise, if you give thanks with your spirit, how can anyone in the position of an outsider^[a] say ^(C)“Amen” to ^(D)your thanksgiving when he does not know what you are saying?

²⁴ But if all prophesy, and an unbeliever or outsider enters, he is convicted by all, he is called to account by all,

²⁷ If any speak in ^(A)a 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.
