What does the Bible say about Hezekiah's illness and healing?

Hezekiah, the king of Judah, faced a terminal illness as stated in 2 Kings 20:1-11. The prophet Isaiah delivered a message from the Lord that he would die. However, Hezekiah turned to God in prayer, pleading for mercy. God, in His sovereign will and grace, decided to extend Hezekiah's life by 15 years, demonstrating His compassion and the power of prayer. This healing serves as a reminder that God's purposes are unchangeable and reflect His glory, as He promised to defend Judah from the Assyrians during the same time.
