John Gill Commentary 2 Kings 20:11

"And Isaiah the prophet cried unto Jehovah; and he brought the shadow ten steps backward, by which it had gone down on the dial of Ahaz." — 2 Kings 20:11 (ASV)

And Isaiah the prophet cried unto the Lord,.... Or prayed, as the Targum; and was very earnest in prayer, that what Hezekiah had desired might be granted:

and he brought the shadow ten degrees backward, by which it had gone down in the dial of Ahaz; Ben Gersom understands it not of the sun itself, but of the shadow of it only; See Gill on "Isaiah 38:8."
