AUV(i)
14 For if I pray in a language [supernaturally], [it is] my spirit that is praying, but my mind does not understand [what I am saying]. [Note: Here Paul raises an objection to the use of a language without the person knowing what he is saying].
15 What should I do then? I will pray with my spirit [i.e. from within], and I will pray with my understanding also [i.e., with a knowledge of what I am saying]. I will sing with my spirit, and I will sing with my understanding also.
