Isaiah 38:1, 5

In those days Hezekiah became sick and was at the point of death. And Isaiah the prophet the son of Amoz came to him, and said to him, “Thus says the LORD: Set your house in order, for you shall die, you shall not recover.”

“Go and say to Hezekiah, Thus says the LORD, the God of David your father: I have heard your prayer; I have seen your tears. Behold, I will add fifteen years to your life.
