In those days Hezeki'ah became sick and was at the point of death. And Isaiah the prophet the son of Amoz came to him, and said to him, "Thus says the LORD, 'Set your house in order; for you shall die, you shall not recover.'"
Then Hezeki'ah turned his face to the wall, and prayed to the LORD, saying,
"Remember now, O LORD, I beseech thee, how I have walked before thee in faithfulness and with a whole heart, and have done what is good in thy sight." And Hezeki'ah wept bitterly.
And before Isaiah had gone out of the middle court, the word of the LORD came to him:
"Turn back, and say to Hezeki'ah the prince of my people, Thus says 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.
And I will add fifteen years to your life. 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."
And Isaiah said, "Bring a cake of figs. And let them take and lay it on the boil, that he may recover."
And Hezeki'ah said to Isaiah, "What shall be the sign that the LORD will heal me, and that I shall go up to the house of the LORD on the third day?"
And Isaiah said, "This is the sign to you from the LORD, that the LORD will do the thing that he has promised: shall the shadow go forward ten steps, or go back ten steps?"
And Hezeki'ah answered, "It is an easy thing for the shadow to lengthen ten steps; rather let the shadow go back ten steps."
And Isaiah the prophet cried to the LORD; and he brought the shadow back ten steps, by which the sun had declined on the dial of Ahaz.
