1 Corinthians 14:2-4

CAB(i) 2 For he who speaks in an unknown tongue speaks not to men, but to God, for no one understands him; however, in the spirit he speaks mysteries. 3 But he who prophesies speaks edification and exhortation and comfort. 4 He who speaks in an unknown tongue edifies himself, but he who prophesies edifies the church.
