1 Corinthians 14:12-14

King James Version

¹² Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church.

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.
