1 Corinthians 14:13-15

Darby Translation

¹³ Wherefore let him that speaks with a tongue pray that he may interpret.

¹⁴ For if I pray with a tongue, my spirit prays, but my understanding is unfruitful.

¹⁵ What is it then? I will pray with the spirit, but I will pray also with the understanding; I will sing with the spirit, but I will sing also with the understanding.
