Taking a closer look at God’s revelation to king Hezekiah, some things become apparent. In verses 22b-25, God recounts the pride of the invading nation, the Assyrians. Then, in verses 26, God deflates their pride by revealing that all of their prosperity and success has actually come about because it was foreordained by His sovereign decree. The Assyrians were nothing more than His chosen instruments to bring about His divine purposes for human history; specifically, the humbling of His chosen people, the nation of Israel, as revealed in verse 27. Yet, despite this fact, the Assyrians chose to rob God of His glory by taking the credit for their success as a nation. God reveals the heart behind such pride in verse 28: “rage against [God].” In other words, as Paul in the New Testament states:
“And since they did not see fit to acknowledge God, God gave them up to a debased mind to do what ought not to be done. They were filled with all manner of unrighteousness, evil, covetousness, malice. They are full of envy, murder, strife, deceit, maliciousness. They are gossips, slanderers, haters of God, insolent, haughty, boastful, inventors of evil, disobedient to parents, foolish, faithless, heartless, ruthless.” – Romans 1.28-31
As a result of their rage and hatred toward God, He then pronounces judgement on the Assyrians in verse 29.
