Working on my Introduction

I brought up a writing project here, which I hope to publish into a novel one day. Aside from plotting the course of the narrative (using the events of Exodus through Deuteronomy as my “map”) and thinking up future dialogue, I really need help getting from Point B to Point C in the Introduction. I know what I’m going to bring up later, but I am going to need an idea.

I’m not willing to post what I have written for the public to see, so please note me if you’d like to offer a hand.
