1 Corinthians 14:2-4

Moffatt(i) 2 For he who speaks in a 'tongue' addresses God not men; no one understands him; he is talking of divine secrets in the Spirit. 3 On the other hand, he who prophesies addresses men in words that edify, encourage, and console them. 4 He who speaks in a 'tongue' edifies himself, whereas he who prophesies edifies the church.
