Isaiah 38:7-8, 22

“ ‘The LORD will do what he says. This is the sign from the LORD to show you: The sun has made a shadow go down the stairway of Ahaz, but I will make it go back ten steps.’ ” So the shadow made by the sun went back up the ten steps it had gone down.

Hezekiah then asked Isaiah, “What will be the sign? What will show that I will go up to the Temple of the LORD?”
