Another promise of healing (and miraculous delivery of that promise) as recorded in the life of one of my favorite Old Testament Kings: Hezekiah –
“In those days Hezekiah became ill and was at the point of death. The prophet Isaiah son of Amoz went to him and said, “This is what the Lord says: Put your house in order, because you are going to die; you will not recover.”
2 Hezekiah turned his face to the wall and prayed to the Lord, 3 “Remember, Lord, how I have walked before you faithfully and with whole hearted devotion and have done what is good in your eyes.” And Hezekiah wept bitterly.
4 Before Isaiah had left the middle court, the word of the Lord came to him: 5 “Go back and tell Hezekiah, the ruler of my people, ‘This is what the Lord, the God of your father David, says: I have heard your prayer and seen your tears; I will heal you. On the third day from now you will go up to the temple of the Lord. 6 I will add fifteen years to your life. And I will deliver you and this city from the hand of the king of Assyria. I will defend this city for my sake and for the sake of my servant David.’”
(From 2 Kings 20)
