I have always been faithful, single-minded, always doing what pleases you - 2 Kings 20:2-3
Hezehiah had been deathly ill for some time and was setting all his affairs in order because his illness was terminal - 2 Kings 2:1
Isaiah had a special connection to God and it would be tempting to plead his case directly with Isaiah
When Isaiah told Hezehiah he was about to die, he went to his private place of prayer and talked directly to the Lord
Hezehiah didn't ask to extend his life but reminded God he had been a good and faithful servant
God decided to extend Hezehiah's life
Hezehiah's willingness to straingth to God saved his his life
