What does Exodus 9:17 mean?

Despite six plagues, Pharaoh remained hardened and defiant. Though his magicians could not compete with divine miracles (Exodus 8:18–19; 9:11), Pharaoh continued to reject the Lord's command. Despite repeated warnings, he refused to release the Hebrew people (Exodus 5:1; 7:16; 8:1, 21; 9:1). Here, the Lord indicates that this is the result of pride. Pharaoh will not accept that he is not the ultimate power above all else. He thinks his will is more important than the lives of the Hebrews, or the demands of their God.

In some ways, Pharaoh's response reflects the attitude of Adam and Eve in the garden of Eden. They were placed in charge of the entire garden with only one restriction: fruit from a particular tree (Genesis 2:16–17). Pharaoh was likewise blessed with many resources. God gave him one command (Exodus 5:1), yet he refused to obey (Exodus 5:2; 7:13–14, 22; 8:15, 19, 32; 9:7) and experienced judgment because of that sin (Genesis 3; Exodus 4:21–23). God's commands are not optional; those who reject His clear commands eventually face consequences. Just as Satan lied to Eve in the garden (Genesis 3:4–6), Pharaoh accepted the lie that he was powerful enough to defy God and do as he pleased.
