1 Corinthians 14:13-19

Authorized (King James) Version

¹³ Wherefore let him that speaketh in an unknown tongue pray that he may interpret. ¹⁴ For if I pray in an unknown tongue, my spirit prayeth 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 thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? ¹⁷ For thou verily givest thanks well, but the other is not edified.

¹⁸ I thank my God, I speak with tongues more than ye 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.
