Isaiah 38:7 (KJV)

Then Hezekiah turned his face toward the wall, and prayed unto the LORD,

And said, Remember now, O LORD, I beseech thee, how I have walked before thee in truth and with a perfect heart, and have done that which is good in thy sight. And Hezekiah wept sore.

Then came the word of the LORD to Isaiah, saying,

Go, and say to Hezekiah, Thus saith the LORD, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will add unto thy days fifteen years.

And I will deliver thee and this city out of the hand of the king of Assyria: and I will defend this city.

Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it was gone down.

The writing of Hezekiah king of Judah, when he had been sick, and was recovered of his sickness:

I said in the cutting off of my days, I shall go to the gates of the grave: I am deprived of the residue of my years.

I said, I shall not see the LORD, even the LORD, in the land of the living: I shall behold man no more with the inhabitants of the world.

Mine age is departed, and is removed from me as a shepherd's tent: I have cut off like a weaver my life: he will cut me off with pining sickness: from day even to night wilt thou make an end of me.
