This verse speaks to the sovereignty and justice of God. It illustrates how God uses nations and leaders to fulfill His purposes, even when they are unaware of their role in His divine plan. Assyria, a powerful empire at the time, was used by God to bring judgment upon Israel and Judah for their disobedience. However, God does not condone the pride and arrogance of Assyria's king. This verse assures us that God sees beyond actions to the intentions of the heart. He is not indifferent to arrogance and pride, even when He uses such individuals or nations for His purposes.
The message is clear: God is in control and will not let pride go unpunished. This serves as a reminder that while God may allow certain events to unfold, He remains just and righteous. His timing and justice are perfect, and He will address all forms of arrogance and wrongdoing. For believers, this is a call to humility and trust in God's overarching plan, knowing that He is both a just judge and a loving Father.
