Brachos 34b: R. Chanina ben Dosa inferred that when his prayer flows smoothly, it is accepted.
Rashi: I will create a new name for him. Since I afflicted him until now, and everyone complained about him, they will call him Shalom Shalom.
Radak: I will make a new saying. Everyone will say Shalom Shalom, and not mention war in the world. This will be after the war of Gog and Magog.
Malbim: Hashem created the entire existence via speech - the breath of His mouth.
What do we learn from "Shalom Shalom la'Rachok vela'Karov"?
Radak citing Sanhedrin 99a #1: Penitent sinners have a greater share in the world to come than Tzadikim who never sinned. The Rachok (one who was far from Hashem, and repented) is in front of the near (one who was always close).
Sanhedrin 99a #2: Penitent sinners have less reward than than Tzadikim who never sinned 'Far' is one who distanced himself from sin. 'Near' is one who was close to sin and distanced himself.
Rashi: Penitent sinners and Tzadikim who never sinned Both of them are equal. One who is aged, and used to My Torah and Avodah from his youth, and one who now came close to repent from his evil way, "u'Refasiv" (Hashem will heal him from his illness and sins).
Radak: This refers to people far from Yerushalayim and close to it. Since the war will be in Yerushalayim, "Shalom" is written next to Rachok.
To whom does "u'Refasiv" refer?
Rashi: Refer to 57:19:2:3.
Radak: It refers to Yisrael, just like v'Erpa'ehu" (18).
Malbim: I heal [the Ba'al Teshuvah or Tzadik] from the illness of his Nefesh, and his bodily pains.
