1 Corinthians 14:13-15

New Revised Standard Version, Anglicised

¹³ Therefore, one who speaks in a tongue should pray for the power to interpret. ¹⁴ For if I pray in a tongue, my spirit prays but my mind is unproductive. ¹⁵ What should I do then? I will pray with the spirit, but I will pray with the mind also; I will sing praise with the spirit, but I will sing praise with the mind also.
