2 Kings 20:9

9 "This will be your sign from God," said Isaiah, "that God is doing what he said he'd do: Do you want the shadow to advance ten degrees on the sundial or go back ten degrees? You choose."

2 Kings 20:9 Meaning and Commentary

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 day:

shall the shadow go forward ten degrees, or go back ten degrees? that 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.

2 Kings 20:9 In-Context

7 Isaiah then said, "Prepare a plaster of figs." They prepared the plaster, applied it to the boil, and Hezekiah was on his way to recovery.

8 Hezekiah said to Isaiah, "How do I know whether this is of God and not just the fig plaster? What confirming sign is there that God is healing me and that in three days I'll walk into The Temple of God on my own legs?"

9 "This will be your sign from God," said Isaiah, "that God is doing what he said he'd do: Do you want the shadow to advance ten degrees on the sundial or go back ten degrees? You choose."

10 Hezekiah said, "It would be easy to make the sun's shadow advance ten degrees. Make it go back ten degrees."

11 So Isaiah called out in prayer to God, and the shadow went back ten degrees on Ahaz's sundial.
