2 Kings 20:4-6

Young's Literal Translation

⁴ And it cometh to pass -- Isaiah hath not gone out to the middle court -- that the word of Jehovah hath been unto him, saying,

⁵ `Turn back, and thou hast said unto Hezekiah, leader of My people: Thus said Jehovah, God of David thy father, I have heard thy prayer, I have seen thy tear, lo, I give healing to thee, on the third day thou dost go up to the house of Jehovah;

⁶ and I have added to thy days fifteen years, and out of the hand of the king of Asshur I deliver thee and this city, and have covered over this city for Mine own sake, and for the sake of David My servant.'
