8 Lo, I am bringing back the shadow of the degrees that it hath gone down on the degrees of Ahaz, by the sun, backward ten degrees:' and the sun turneth back ten degrees in the degrees that it had gone down.

Matthew Henry's Commentary on Isaiah 38:8

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.
