5 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. 6 And I will deliver thee and this city out of the hand of the king of Assyria: and I will defend this city. 7 And this shall be a sign unto thee from the Lord, that the Lord will do this thing that he hath spoken; 8 Behold, I will bring again the shadow of the degrees, which is gone down in the sun dial [1] of Ahaz, ten degrees backward. So the sun returned ten degrees, by which degrees it was gone down.
5 "Go and tell Hezekiah, 'This is what the Lord, the God of your father David, says: I have heard your prayer and seen your tears; I will add fifteen years to your life. 6 And I will deliver you and this city from the hand of the king of Assyria. I will defend this city. 7 " 'This is the Lord's sign to you that the Lord will do what he has promised: 8 I will make the shadow cast by the sun go back the ten steps it has gone down on the stairway of Ahaz.' " So the sunlight went back the ten steps it had gone down.
5 "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.
5 "Go and speak with Hezekiah. Give him this Message from me, God, the God of your ancestor David: 'I've heard your prayer. I have seen your tears. Here's what I'll do: I'll add fifteen years to your life. 6 And I'll save both you and this city from the king of Assyria. I have my hand on this city. 7 "'And this is your confirming sign, confirming that I, God, will do exactly what I have promised. 8 Watch for this: As the sun goes down and the shadow lengthens on the sundial of Ahaz, I'm going to reverse the shadow ten notches on the dial.'" And that's what happened: The declining sun's shadow reversed ten notches on the dial.
5 "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. 6 I will deliver you and this city from the hand of the king of Assyria, and I will defend this city." ' 7 And this is the sign to you from the Lord, that the Lord will do this thing which He has spoken: 8 Behold, I will bring the shadow on the sundial, which has gone down with the sun on the sundial of Ahaz, ten degrees backward." So the sun returned ten degrees on the dial by which it had gone down.
5 "Go back to Hezekiah and tell him, 'This is what the Lord, the God of your ancestor David, says: I have heard your prayer and seen your tears. I will add fifteen years to your life, 6 and I will rescue you and this city from the king of Assyria. Yes, I will defend this city. 7 "'And this is the sign from the Lord to prove that he will do as he promised: 8 I will cause the sun's shadow to move ten steps backward on the sundial of Ahaz!'" So the shadow on the sundial moved backward ten steps.

(Read Isaiah 38:1-8)
When we pray in our sickness, though God send not to us such an answer as he here sent to Hezekiah, yet, if by his Spirit he bids us be of good cheer, assures us that our sins are forgiven, and that, whether we live or die, we shall be his, we do not pray in vain. See 2 Kings 20:1-11.
