The New John Gill Exposition of the Entire Bible2 Kings 20:9
And Isaiah said, this sign shalt thou have of the Lord, that
the Lord will do the thing that he hath spoken…
Cure him of his
disorder, so that he should be able to go to the temple on the third
shall the shadow go forward ten degrees, or go back ten degrees?
is, the shadow of the sun on a dial plate; it was left to his option to
choose which he would, as the confirming sign of his recovery.
