Isaiah 38:3-6

and said, “Remember now, O LORD, I pray, how I have walked before You in truth and with a loyal heart, and have done what is good in Your sight.” And Hezekiah wept bitterly. And the word of the LORD came to Isaiah, saying, “Go and tell Hezekiah, ‘Thus says the LORD, the God of David your father: “I have heard your prayer, I have seen your tears; surely I will add to your days fifteen years. I will deliver you and this city from the hand of the king of Assyria, and I will defend this city.” ’
