2 Kings 20:1-5

In those days Hezekiah became mortally ill. And Isaiah the prophet, the son of Amoz, came to him and said to him, “This is what the Lord says: ‘Set your house in order, for you are going to die and not live.’ ”

Then he turned his face to the wall and prayed to the Lord, saying,

“Please, Lord, just remember how I have walked before You wholeheartedly and in truth, and have done what is good in Your sight!” And Hezekiah wept profusely.

And even before Isaiah had left the middle courtyard, the word of the Lord came to him, saying,

“Return and say to Hezekiah the leader of My people, ‘This is what the Lord, the God of your father David says: “I have heard your prayer, I have seen your tears; behold, I am going to heal you. On the third day you shall go up to the house of the Lord.
