What does Exodus 8:11 mean?
Moses has agreed to advocate for the end of the plague of frogs (Exodus 8:5–6) now that Pharaoh has claimed he will release the Israelite slaves (Exodus 8:8). Pharaoh was told to select when the disaster would end, so that there would be no doubt that it was done by the power of God (Exodus 8:9–10).As with many of the plagues, this incident emphasizes the power of the Lord above that of imaginary deities and human kings. Despite Pharaoh's power and spite (Exodus 5:6–9), he can only give orders from one human to other humans. His magicians have some ability (Exodus 7:10–12, 22–23), but not enough to stop the current trouble. Egyptian religion includes deities like Heqet, the frog goddess, but she is ineffective. The same was true of Hapi and Khnum, idols connected to the Nile River (Exodus 7:19–20).
Pharaoh is used as an example of a lesson he himself will never really learn. Only the most extreme pressure (Exodus 3:19–20) will lead him to release the slaves (Exodus 8:15). Even that will be temporary (Exodus 14:5–9), resulting in brutal defeat and death (Exodus 14:27–29). Stubbornness against God never leads to positive ends. Sooner or later, there comes a point of no return followed by disaster (Proverbs 29:1).
