The fruit of the lips... — The words point primarily to the praise and thanksgiving of the pardoned penitent (comp. Hosea 14:2; Hebrews 13:15), but include also all true utterances of the wise of heart (Proverbs 10:31). All these alike have their origin in the creative fiat of Jehovah, which proclaims “peace” (i.e., salvation) to all, whether near or far, Jews in Jerusalem, or Jews in exile, or (as in Ephesians 2:17) the Gentiles whose distance was that of spiritual remoteness. The message of healing is for all.
