1 Corinthians 14:14-15 For if I pray in an unknown tongue, my spirit prays, but my understanding is unfruitful.

AKJV⁽ⁱ⁾ ¹⁴ For if I pray in an unknown tongue, my spirit prays, 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.
