Historic pastoral reading
Healing here is the wound of sin being dealt with. Physical healings in the Gospels sit beside that, they do not empty hospitals.
Isaiah 53:4-5
4 Surely he has borne our sickness and carried our suffering; yet we considered him plagued, struck by God, and afflicted.
5 But he was pierced for our transgressions. He was crushed for our iniquities. The punishment that brought our peace was on him; and by his wounds we are healed.
4 Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted.
5 But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
