2 Kings 20:4-5

And it came to pass, afore Isaiah was gone out into the middle court, that the word of the LORD came to him, saying, 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.
