¹⁴ For if I pray in a tongue, my spirit prayeth, but my understanding is unfruitful.

² For he that speaketh in a tongue speaketh not unto men, but unto God; for no man understandeth; but in the spirit he speaketh mysteries.

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 if thou bless with the spirit, how shall he that filleth the place of the unlearned say the Amen at thy giving of thanks, seeing he knoweth not what thou sayest?

¹⁹ howbeit in the church I had rather speak five words with my understanding, that I might instruct others also, than ten thousand words in a tongue.
