Jeremiah 8:22:

Is there no balm in Gilead; is there no physician there? why then is not the health of the daughter of my people recovered?

Notes on Jeremiah 8:22:

God, of course, was Israel’s Physician.  Why did the people not let Him heal them?  In the context of this verse, there is no indication that the sickness refers to bodily sickness except as an allegory for the terrible condition of Israel, although physical healing would have followed repentance because God was their Physician.
