Charles Ellicott Commentary Isaiah 57:19

"I create the fruit of the lips: Peace, peace, to him that is far off and to him that is near, saith Jehovah; and I will heal him." — Isaiah 57:19 (ASV)

The fruit of the lips ... —The words point primarily to the praise and thanksgiving of the pardoned penitent (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 the Gentiles whose distance was that of spiritual remoteness. The message of healing is for all.
