The study of the Pentateuch will be very interesting, especially the books of Genesis, Exodus, and Numbers, as we will be able to see in action the elements of the Documentary Hypothesis: the theory of the assembling of four originally separate texts to constitute what we now know as the Pentateuch. If you aren't familiar with the hypothesis, this article is decent as an introduction.
https://en.wikipedia.org/wiki/Documentary_hypothesis Yes, I know that now there are other theories out there, but I have read them, and to me the Documentary Hypothesis still makes the most sense.
Here in the first 3 chapters, we get some of the seeds of the theory. We have 2 separate and complete versions of the story of creation. The first is in Genesis 1:1 - 2:3, and the second one is in Genesis 2:4 - 25. The first is from the Priestly source (known as P), which is relatively late, and the second one is from the Yahwist source (known as J), which is the earliest source. Some of the characteristics of P include the use of the Hebrew word
elohim for "God" and a depiction of God as transcendent and non-anthropomorphic; God does not personally do things, but rather commands them to happen and they do. In the P source, a person could not have intimate knowledge of God, because God was too transcendent and non-human-like. Some of the characteristics of J include the use of the personal name of God, the Tetragrammaton (later translated as
adonai or The LORD in English translations, to avoid depiction of The Name), as well as depicting God in anthropomorphic terms. God makes and forms things, and places things in various locations, and makes things for the humans. He makes Adam by hand, and breathes life into him. He then takes a rib from Adam and makes Eve. He has a personal and intimate relationship with Adam & Eve.
Then, of course, in Chapter 3 (also from J), we get the story of the Temptation and the Fall. What a brilliant depiction of human nature this is. I know that many Christians point to this story as the foundation of the concept of sin from which we need saving, but please try to read the story for what it is - there is no such concept in the text. There is no mention in the text that the serpent is Satan. He is just a serpent. All of that stuff is later Christian retconning.
