What does the Bible say about God's purpose in the plagues of Egypt?

In Exodus 9:16, God tells Pharaoh that He raised him up specifically to show His power and for His name to be declared throughout the earth. The plagues serve a dual purpose: they are a demonstration of God's might and a warning to both Pharaoh and the nations. Rather than merely punishing Pharaoh for his sins, God is making an example of him for all who refuse to heed His warnings. This broader narrative emphasizes that God's actions in history are ultimately for His glory and purpose.
