Isaiah Chapter 38 Verse 7And this [shall be] a sign unto thee from the LORD, that the LORD will do this thing that he hath spoken;

For I will defend this city to save it for mine own sake, and for my servant David's sake.

Then the angel of the LORD went forth, and smote in the camp of the Assyrians a hundred and fourscore and five thousand: and when they arose early in the morning, behold, they [were] all dead corpses.

In those days was Hezekiah sick unto death. And Isaiah the prophet the son of Amoz came unto him, and said unto him, Thus saith the LORD, Set thine house in order: for thou shalt die, and not live.

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.

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.

I reckoned till morning, [that], as a lion, so will he break all my bones: from day [even] to night wilt thou make an end of me.

Like a crane [or] a swallow, so did I chatter: I did mourn as a dove: mine eyes fail [with looking] upward: O LORD, I am oppressed; undertake for me.

What shall I say? he hath both spoken unto me, and himself hath done [it]: I shall go softly all my years in the bitterness of my soul.

O Lord, by these [things men] live, and in all these [things is] the life of my spirit: so wilt thou recover me, and make me to live.

Behold, for peace I had great bitterness: but thou hast in love to my soul [delivered it] from the pit of corruption: for thou hast cast all my sins behind thy back.
