“In those days was Hezekiah sick unto death. And the prophet Isaiah the son of Amoz came to him, and said unto him, Thus saith the LORD, Set thine house in order; for thou shalt die, and not live.”
King James Version (KJV)
20:1 Those days - In the year of the Assyrian invasion. Set, &c. - Make thy will, and settle the affairs of thy family and kingdom. Not live - Such threatenings, though absolutely expressed, have often secret conditions.
