2 Kings 20:1-11

In those days was Hezekiah sick unto death. And Isaiah the prophet the son of Amoz came to him, and said unto him, Thus saith Jehovah, Set thy house in order; for thou shalt die, and not live. Then he turned his face to the wall, and prayed unto Jehovah, saying, Remember now, O Jehovah, I beseech thee, how I have walked before thee in truth and with a perfect heart, and have done that which is good in thy sight. And Hezekiah wept sore. And it came to pass, before Isaiah was gone out into the middle part of the city, that the word of Jehovah came to him, saying, Turn back, and say to Hezekiah the prince of my people, Thus saith Jehovah, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will heal thee; on the third day thou shalt go up unto the house of Jehovah. And I will add unto 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 mine own sake, and for my servant David’s sake. And Isaiah said, Take a cake of figs. And they took and laid it on the boil, and he recovered. And Hezekiah said unto Isaiah, What shall be the sign that Jehovah will heal me, and that I shall go up unto the house of Jehovah the third day? And Isaiah said, This shall be the sign unto thee from Jehovah, that Jehovah will do the thing that he hath spoken: shall the shadow go forward ten steps, or go back ten steps? And Hezekiah answered, It is a light thing for the shadow to decline ten steps: nay, but let the shadow return backward ten steps. And Isaiah the prophet cried unto Jehovah; and he brought the shadow ten steps backward, by which it had gone down on the dial of Ahaz.
