Can God die

[Michael Joseph]

I don't think that chapter 4 of Genesis is narrated chronologically.
Daughters are often not mentioned in the OT and I believe that Cain married his sister.
Of course I cannot prove this, because the Bible does not tell us.
Cain's fear in Genesis 4:14 would have been from his own family members.

I agree that the narrative is mysterious in this regard, but I see no reason to believe that there were more than one Adam and Eve.

Interestingly, the Kebra Nagast says that one reason Cain was envious of Abel was because Abel got to marry the sister with the beautiful face, which resembled Cain's.
I don't know which parts, if any, of the Kebra Nagast are inspired.
I don't consider it good evidence.

Adam and Eve were expelled from Eden before they had children.
Who named the land Nod is not specified.
Nod means wandering.

Notice that all the names in chapter 4 are highly symbolical.
Cain means smith.
Abel (Hevel) means breath, vapor.
An interesting factoid:
The second verse of Ecclesiastes echoes Abel's name in the Hebrew. It starts out "hevel havalim".

I do not rely on Kebra Negast at all except that it is a 2nd Witness to the Giants in the Earth and the Children the Women bore to those fallen Angels.

In the Book of Enoch - included in many bibles prior to the Council at Nice - says Who is this one who cries day and night? - That is Abel who cries out for vengeance.

Stop and think of all of the lineage that would have come thru Abel that was cut-off by Cain. Murder is a terrible terrible thing.
