Isaiah 57:19

I create the fruit of the lips - "The sacrifice of praise," saith St. Paul, Hebrews 13:15, "is the fruit of the lips." God creates this fruit of the lips, by giving new subject and cause of thanksgiving by his mercies conferred on those among his people, who acknowledge and bewail their transgressions, and return to him. The great subject of thanksgiving is peace, reconciliation and pardon, offered to them that are nigh, and to them that are afar off, not only to the Jew, but also to the Gentile, as St. Paul more than once applies those terms, Ephesians 2:13, Ephesians 2:17. See also Acts 2:39.

Peace to him that is far off "That is, to the penitent; and to him that is near, i.e., the righteous." - Kimchi.

I create the fruit of the lips - The Chaldee and Syriac render this, 'The words of the lips.' The 'fruit' of the lips is that which the lips produce, that is, words; and the reference here is doubtless to offerings of praise and thanksgiving. See Hebrews 13:15; where the phrase, 'fruit of the lips' (καρπὸς χειλέων karpos cheileōn), is explained to mean praise. Compare Hosea 14:2, where the expression, 'we will render the calves of the lips,' means that they would offer praise. The sense here is, that God bestowed such blessings as made thanksgiving proper, and thus, he 'created the fruit of the lips.'

Peace, peace - The great subject of the thanksgiving would be peace. The peace here referred to probably had a primary reference to the cessation of the calamities which would soon overwhelm the Jewish nation, and their restoration again to their own land. But the whole strain of the passage also shows that the prophet had a more general truth in his view, and that he refers to that peace which would diffuse joy among all who were far off, and those who were near. Paul evidently alludes to this passage in Ephesians 2:14-17. Thus understood, the more general reference is to the peace. which the Messiah would introduce, and which would lay the foundation for universal rejoicing and praise (compare the notes at Isaiah 2:4; Isaiah 9:5).

To him that is far off - Applied by the apostle Paul to the Gentiles, who are represented as having been far off from God, or as aliens or strangers to him Ephesians 2:17.

And to him that is near - That is, to the Jewish people Ephesians 2:17, represented as having been comparatively near to God in the enjoyment of religious privileges.

57:19 I create - I will by my almighty power produce. Peace - That peace which is not wrought by mens hands, but only by God's lips or word.The doubling of the word signifies the certainty and abundance this peace.Far off - To the Gentiles who are far from God, as well as to the Jews, who are called a people near unto God, Psalms 148:14 .
