I have read it and the whole Bible. I am not convinced you have since Hell was supposedly created for Satan and his Angels and not Adam and Eve. That said, Hell was a Pagan idea that didn't get Biblical support until the New Testament.
It probably isn't helpful to use the word hell as it has been used to translate or refer to so many different words (sheol, abaddon, ge hinnom, hades, gehenna, tartarus, abyssos, the lake of fire). These are not identical concepts.
RE: Satan and hell.
Satan and his angels were bound (Revelation 20) and tossed into the pit (
abyssos) which is likened to a prison. This may/may not be the same as
Tartarus (2 Peter 2:4). After the 1000 year reign of Messiah, at that time, Satan, his angels, death,
hades, and those who are judged and not found in the book of life are thrown into the
lake of fire (Revelation 20).
Using hell for all these words is just confusing: Satan and his angels were bound (Revelation 20) and tossed into
hell which is likened to a prison. This may/may not be the same as
hell (2 Peter 2:4). After the 1000 year reign of Messiah, at that time, Satan, his angels, death,
hell, and those who are judged and not found in the book of life are thrown into the
hell (Revelation 20).
Sloppy use of words has hellish results.
RE: Adam and Eve and hell. In this case the lake of fire is for apostate heavenly hosts and for humans not in the book of life. Whether that was the plan for all lost humanity from the beginning or only since Revelation is kind of a moot point (God, since the publication of that book, has continued to allow humans to be born who would be destined to the lake of fire so the same general charge stands: God makes humans destined for the lake of fire.)
RE: "Hell was a Pagan idea that didn't get Biblical support until the New Testament". Not really. Exile is one of the first Biblical themes. The grave, a book of life, life after death, and judgment are all themes that can be found in the Hebrew Bible, most very early. Even if the exodus is denied there is clearly connections between Israel and Egypt (everything from loanwords to an intimate knowledge of the flood inundation cycle and its relation to Egypt's gods; see also the Armana Letters showing significant diplomacy between Canaan and Egypt in the 14th c. BCE and scarabs found in Canaan) which begs the question: Why would Israel have no concept of an afterlife considering Egypt's preoccupation with such? It seems clear to me there is a subtext of eternal life in the Hebrew Bible, to wit one of the first stories is about the Tree of Life. It is sloppy scholarship to insinuate borrowing as trees of life, underworlds, paradise, etc. are all pervasive concepts throughout the ancient Near East but developed differently in various religions. Probably the best example, as the Hebrew Bible well documents such, is the Temple (and tabernacle before which). It is a common tripartite long room design as so common in the Levant but how it functions (especially the image of God), food/sacrifices, etc. communicates and functions very differently. Form and function are not the same thing, a rule that extends to a lot of shared imagery and conceptual categories.
