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
7 "This shall be the sign to you from the Lord, that the Lord will do this thing that he has promised: 8 Behold, I will make the shadow cast by the declining sun on the dial of Ahaz turn back ten steps." So the sun turned back on the dial the ten steps by which it had declined.
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.
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.
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.

Commentary on Isaiah 38:1-8
(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.
