Yes, specifically the last strike against Egypt. In more detail: A literalist has a hard time getting a moral out of the story that God "hardens" the Pharaoh's heart explicitly so that he can use the Pharaoh's lack of action as excuse for a further demonstration of power, which involves a painful punishment of children for something a tyrann ruling their parents did. (In fact, I saw literalists attempting that, and the result is either very disgusting or interprets words and sentences in rather strange ways.) But if you know that none of this happened, and furthermore that when this was written, Egypt was a giant empire that - led by a god-king - used to threaten and ultimately pillage and conquer small Judea, you will see that this story is really about giving self-respect and determination to Judeans (and others in a similar position) - by way of "my God is more powerful than this mighty god-king".

I think one reason (hehe) for mythological stories is to provide structure and shelter from the nasty world outside. It offers explanation that is comforting in a situation that is cruel.

Ah! PeWi, then I took you more seriously than yourself :-)
