Great day of study in Exodus 11 through 13.
These chapters have the most amazing alteration of literary styles.
They alternate between narrative of events in real time (the story) and God given points of ceremonial instruction (the story breaks and God speaks through the author as if to say “See what is happening in the story here? Based on these events I now decree that you have such and such particular ceremony to remember it perpetually in the future.”), more story which culminates the first nine plagues with the climactic tenth, and more interruption about what the death of the firstborn in the actual story should mean in the future when Israel enters her promised land.
This literary feature serves to show us that this is one of the most important sections in the entire Pentateuch.
We will be all over it this Sunday morning.
