1 Corinthians 14:2-4

Thomson(i) 2 For he who speaketh in a strange language, speaketh not to men but to God: for none understandeth; and with a spirit he speaketh mysteries. 3 But he who prophesieth, speaketh to men edification, and exhortation, and consolation. 4 He who speaketh in an unknown tongue edifieth himself; but he who prophesieth, edifieth a congregation.
