What the Bible says about Exile of Israel
(From Forerunner Commentary)
Goodness is used in this context to convey the pleasant, joyful, and overwhelmingly positive effect of blessings on the people of Israel after their exile and captivity.
This exile of Israel will eventually result in both a physical and spiritual healing, testifying of God's awesome goodness to a previously rebellious people, who will receive incredible blessings upon repentance. Verse 6 says, "Behold, I will bring it [Israel] health and healing; I will heal them and reveal to them the abundance of peace and truth." The word "health" in this verse is literally "new flesh" in the original Hebrew. Their exile will have a healing effect, and the wounds of Israel will be wrapped in peace and security.
