1 Corinthians

¹³Wherefore let him that speaketh in a tongue pray that he may interpret. ¹⁴For if I pray in a tongue, my spirit prayeth, but my understanding is unfruitful. 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 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? ¹⁷For thou verily givest thanks well, but the other is not edified. ¹⁸I thank God, I speak with tongues more than you all: ¹⁹howbeit 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.
