2 Kings 20:8 WBT

⁶  And I will add to thy days fifteen years; and I will deliver thee and this city out of the hand of the king of Assyria; and I will defend this city for my own sake, and for my servant David's sake.

⁷  And Isaiah said, Take a lump of figs. And they took and laid [it] on the boil, and he recovered.

⁸  And Hezekiah said to Isaiah, What [shall be] the sign that the LORD will heal me, and that I shall go up into the house of the LORD the third day?

⁹  And Isaiah said, This sign shalt thou have of the LORD, that the LORD will do the thing that he hath spoken: shall the shadow go forward ten degrees, or go back ten degrees?

¹⁰  And Hezekiah answered, It is a light thing for the shadow to go forward ten degrees: no, but let the shadow return backward ten degrees.
