2nd Kings 20:5

2 Then he turned his face to the wall, and prayed unto the LORD, saying,

3 I beseech thee, O LORD, remember now 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.

4 And it came to pass, afore 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 saith the LORD, 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 the LORD.

6 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.

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 unto 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?
