“But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God.”
King James Version (KJV)
14:28 Let him speak - That tongue, if he find it profitable to himself in his private devotions.
1Co 14:28 But if there be no interpreter. In that case the rule, "Let all things be done to edifying" (1Co 14:26), will force the speaker in tongues to keep silence in the church. He may speak somewhere else, or in his soul, but not in the assembly of the saints.
