Behold, I will bring it health and cure, and I will cure them,.... That is, the church of God, the members of it, typified by Jerusalem; and it is to be understood of the healing of their spiritual maladies, the diseases of sin, through the blood of the Messiah, who should arise with healing in his wings; that is, with remission of sin, which is often meant by healing in Scripture: Christ is the physician; his blood the balm in Gilead, which being applied to those that are diseased with sin, to sin sick souls, it makes an effectual cure of them; so that they shall not say they are sick, because their iniquities are forgiven them; see Ps 103:3;and will reveal unto them the abundance of peace and truth; the same with "grace and truth", which are come by Christ, Joh 1:17; under the Old Testament, these were figured out by types and shadows; but not revealed clearly, as under the New Testament, to which this prophecy belongs.
"Peace" may intend peace made with God by the blood of Christ; peace of conscience, which he gives, and arises from a sense of pardon and atonement by his blood, and justification by his righteousness; and all kind of spiritual welfare, prosperity, and happiness; of which there will be an abundance, especially in the latter days of the Messiah, Ps 72:8.
"Truth" may design the faithfulness of God, in fulfilling all his promises and prophecies concerning the Messiah, and salvation by him, and may stand opposed to the types and shadows of the old law; and include the Gospel, the word of truth, and all the doctrines of it; which are clearly and fully revealed by the spirit of truth, wisdom, and revelation, in the knowledge of Christ.
Here begins the account of the great, mighty, and hidden things the Lord promised to show the prophet, Jer 33:3.
