The stunning victories of God over the Egyptians. God hardens their hearts and they pursue the Israelites despite all the clear messages of the power of God above their gods.
God makes it dark, he jams the wheels of their chariots. He leads the chase a though a sea which is a wall of water for the Israelites’ and downs the Egyptians.
They are told to stop running, virtually baiting the Egyptians to come and try to get them back. But the plagues haven’t convinced the Israelites of god’s power. Keith green seized on this as a metaphor. They wanna go back to slavery, to Egypt. They are terrified when the Egyptians pursue them.
It’s worth remembering when i lose yet another argument with an atheist. You would think the Israelites would be the strongest believers ever, but they constantly question Gods power.
