Hezekiah's prayer begins by addressing God with specific titles: "Lord of hosts," "God of Israel," "who sits between the cherubim." Commentators explain these are not just formalities. Each title is a declaration of faith meant to build confidence. He appeals to God's immense power ("Lord of hosts"), His covenant relationship ("God of Israel"), His merciful presence (symbolized by the ark's cherubim), and His universal authority as Creator. This teaches us to ground our prayers in who God has revealed Himself to be.
