4 Isaiah left the king, but before he had passed through the central courtyard of the palace the Lord told him
5 to go back to Hezekiah, ruler of the Lord's people, and say to him, “I, the Lord, the God of your ancestor David, have heard your prayer and seen your tears. I will heal you, and in three days you will go to the Temple.
6 I will let you live fifteen years longer. I will rescue you and this city of Jerusalem from the emperor of Assyria. I will defend this city, for the sake of my own honour and because of the promise I made to my servant David.”
7 Then Isaiah told the king's attendants to put on his boil a paste made of figs, and he would get well.
8 King Hezekiah asked, “What is the sign to prove that the Lord will heal me and that three days later I will be able to go to the Temple?”
9 Isaiah replied, “The Lord will give you a sign to prove that he will keep his promise. Now, would you prefer the shadow on the stairway to go forward ten steps or go back ten steps?”
10 Hezekiah answered, “It's easy to make the shadow go forward ten steps! Make it go back ten steps.”
