1 Corinthians 14:13-15

New King James Version

¹³ Therefore let him who speaks in a tongue pray that he may ^(A)interpret. ¹⁴ For if I pray in a tongue, my spirit prays, but my understanding is unfruitful. ¹⁵ What is the conclusion then? I will pray with the spirit, and I will also pray with the understanding. ^(B)I will sing with the spirit, and I will also sing ^(C)with the understanding.
