I think they key to understanding the Torah is the talk of envy between Cain over Abel, and then Seth being appointed and set by God, and Enoch in the image of God, and then get into understanding of how people deviated by taking the name of God and naming themselves with it, and then the story that surrounds the chosen ones from the offspring of Abraham which makes way to understanding the promise to Aaron and his family. Aaron and his family were promised with a true promise, even though the Torah goes 180 against it afterwards, it's obvious that the whole talk of Abraham was to set up Aaron and his family.
And you must understand the position of the "the one who God will send" with respect to the promise through Ishmael, and the 12 princes, and it's protective side point that Ishmael had twelve sons with the same number of the twelve princes promised. It was a way of protecting the promise of 12 anointed pure Kings that would inherit a true King from Ishmael, and Gospels clarify who the true anointed Kings are with Jesus being an example of being one, and they were the way to life, the truth, and no knows God or get's to God except through them.
