1 Corinthians 14:2-4

Lamsa(i) 2 For he who speaks in an unknown tongue speaks not to men, but to God; for no man understands what he says; however through the Spirit he speaks mysteries. 3 But he who prophesies speaks to men for edification, encouragement, and comfort. 4 He who speaks in an unknown tongue edifies himself; but he who prophesies edifies the church.
