This section is unfinished. But it was an awful lot of work so far, and I'm very very fond of it. Maybe someone will get some benefit from it, till the day when I can get back to working on it.
Here's the idea: The first document goes through Breishis, posuk by posuk, parsha by parsha. At each verse, I list the themes that I noticed that appear elsewhere.
The second document takes those themes, in alphabetical order, and lists all the verses that suggest the same theme.
There are a lot of them, and what I found is just a tiny drop in the sea; whenever I go back to look at it, I find more, and hear more from others. And I'm only about halfway through Bereishis anyhow. And I skipped the creation of the world; it links to everything there is and was just too overwhelming to start with.
And eventually all the themes should have hyperlinks, to take you automatically to the other document, and vice versa.
But I hope it's a start.
