Isa 38:2-5
Then Hezekiah turned his face to the wall and prayed to the LORD: "O LORD, remember how faithfully and wholeheartedly I conducted myself in your presence, doing what was pleasing to you!" And Hezekiah wept bitterly. Then the word of the LORD came to Isaiah: "Go, tell Hezekiah: Thus says the LORD, the God of your father David: I have heard your prayer and seen your tears. I will heal you: in three days you shall go up to the LORD'S temple; I will add fifteen years to your life.
