Jeremiah 30:17:

For I will restore health unto thee, and I will heal thee of thy wounds, saith the LORD; because they called thee an Outcast, saying, This is Zion, whom no man seeketh after.

Notes on Jeremiah 30:17:

Because this passage comes in a chapter full of metaphors of having no medicine, having an incurable bruise and a grievous wound, it can be taken figuratively.  However, because it refers to the restoration of Israel after the Tribulation (“the time of Jacob’s trouble”), we know from other Scriptures about the Millennium that this passage can also be taken literally.  You should consider it a prophecy about the future as opposed to a direct healing promise to the Church today.
