11. Therefore if I know not the meaning of the voice, I shall be unto him that speaks a foreigner, and he that speaks shall be a foreigner unto me.
12. Even so you, since you are zealous of spiritual gifts, seek that you may excel to the edifying of the church.
13. Therefore let him that speaks in an unknown tongue pray that he may interpret.
14. For if I pray in an unknown tongue, my spirit prays, but my understanding is unfruitful.
15. What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
16. Else when you shall bless with the spirit, how shall he that occupies the place of the unlearned say Amen at your giving of thanks, seeing he understands not what you said?
17. For you verily give thanks well, but the other is not edified.
18. I thank my God, I speak with tongues more than you all:
19. Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.
