What does Exodus 9:34 mean?
In response to some earlier plagues, Pharaoh promised to release the Hebrew slaves. Every time, he broke his word and kept them captive (Exodus 8:8, 15, 25, 32). In other instances, he didn't even pretend to cooperate (Exodus 5:2; 7:13–14, 22; 8:19). After six prior plagues (Exodus 7:21; 8:6, 17, 24; 9:6, 10), Egypt has been thrashed by hail and lightning (Exodus 9:24–25). Pharaoh begged for relief, promising freedom (Exodus 9:28). God ended the storm when Moses stretched out his hands, but Moses—and God—knew this was another insincere deception (Exodus 9:29–30).Though Egypt's king is the primary culprit, his advisors and fellow Egyptians are not blameless in these events. This verse notes that they defied God "again." This parallels Pharaoh's confession (Exodus 9:27) that they were in error. The chain of disaster will begin to weaken Egyptian resolve. When the next plague is threatened, advisors will suggest negotiation (Exodus 10:7).
Worse, this is when Pharaoh crosses a terrible line and loses the opportunity to repent (Proverbs 29:1). Until now, he has defied God using his own free will—with one exception (Exodus 9:12). God is open to anyone who seeks Him in sincerity and faith (John 6:37). He forgives every sin of His born-again people (John 3:16–17). However, no one has unlimited time to respond to His call (Luke 13:25; Hebrews 9:27; Isaiah 55:6). After this rebellion, the Lord will provide no chance for Pharaoh to avoid judgment (Exodus 4:21; 10:1). Instead, the king will be used as a tool to display the wrath of God (Exodus 10:20, 27; 11:10; 14:8–9).
