For if I pray in a tongue my spirit prays, but my intellect is unfruitful.
For he who speaks in a tongue speaks not to men, but to God, for no man hears, but in spirit he speaks mysteries.
Yet in an assembly I would rather speak five words with my intellect, so that I might also make others understand, than countless words in a tongue.
Therefore let him who speaks in a tongue pray that he may interpret.
