AKJV⁽ⁱ⁾ ⁴ And it came to pass, before Isaiah was gone out into the middle court, that the word of the LORD came to him, saying, ⁵ Turn again, and tell Hezekiah the captain of my people, Thus said the LORD, the God of David your father, I have heard your prayer, I have seen your tears: behold, I will heal you: on the third day you shall go up to the house of the LORD. ⁶ And I will add to your days fifteen years; and I will deliver you 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 shall you have of the LORD, that the LORD will do the thing that he has 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 down ten degrees: no, but let the shadow return backward ten degrees. ¹¹ And Isaiah the prophet cried to the LORD: and he brought the shadow ten degrees backward, by which it had gone down in the dial of Ahaz.
