8:22 [Is there] no balm {r} in Gilead; [is there] no physician there? why then is not the health of the daughter of my people recovered?
(r) Meaning,that no man's help or means could save them: for in Gilead was precious balm, Jer 46:11 or else deriding the vain confidence of the people, who looked to their priests for help, who would have been the physicians of their soul, and dwelt at Gilead, Ho 6:8.
8:14-22 At length they begin to see the hand of God lifted up. And when God appears against us, every thing that is against us appears formidable. As salvation only can be found in the Lord, so the present moment should be seized. Is there no medicine proper for a sick and dying kingdom? Is there no skilful, faithful hand to apply the medicine? Yes, God is able to help and to heal them. If sinners die of their wounds, their blood is upon their own heads. The blood of Christ is balm in Gilead, his Spirit is the Physician there, all-sufficient; so that the people may be healed, but will not. Thus men die unpardoned and unchanged, for they will not come to Christ to be saved.
