15What 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.
16Else if you bless with the spirit, how will he who fills the place of the unlearned say the "Amen" at your giving of thanks, seeing he doesn`t know what you say?
17For you most assuredly give thanks well, but the other person is not built up.
18I thank my God, I speak with other languages more than you all.
19However in the assembly I would rather speak five words with my understanding, that I might instruct others also, than ten thousand words in another language.
20Brothers, don`t be children in mind, yet in malice be babies, but in mind be men.
21In the law it is written, "By men of strange languages and by the lips of strangers I will speak to this people. Not even thus will they hear me, says the Lord."
