Wherefore let him that speaketh in an unknown tongue pray that he may interpret.
Explain, 'Let him who speaketh with an unknown tongue (in prayer) pray with the purpose that he may interpret.' This explanation is needed by the logical connection with "pray in an unknown tongue" (1 Corinthians 14:14). Though his words be unintelligible, let him in them pray for the gift of interpreting, which will make them "edifying" to "the church" (1 Corinthians 14:12). It was only when they could interpret that the, "understanding" accompanied the "tongue" (1 Corinthians 14:15; 1 Corinthians 14:19).
