Let's not also forget Cain killed his brother Abel and was excommunicated. Do you think Adam & Eve would allow Cain to marry one of his siblings after he had already killed one?
@Tumah and
@crossfire
Allow?
If that was the case. Adam's genealogy and Cains genealogy would be the same. If Cain married his sister and had kids, there would not be need for 2 separate genealogies listed in Genesis.
Adam's descendants would be Cain's as well that's true. But Seth's descendants would not be.
The genealogy of Gen. 4 is describing Cain's descendants, presumably to get to Lemech.
The genealogy of Gen. 5 is describing Seth's descendants, presumably to get to Noah.
The sons and daughters spoke of in Genesis 5:3-5 are Seth's sons and daughters. Which are Adams grand children.
Who did Seth marry? Where did his wife come from?
Same story. Adam had
multiple daughters.
Here's a cute little thing:
Lev. 20:17
And a man who takes his sister, the daughter of his father or the daughter of his mother and sees her nakedness and she sees his nakedness, it is a
ḥesed, and they shall be cut off from the eyes of the nation. He revealed his sister's nakedness, he shall carry his sin.
Psa. 89:3
[The] world is built on
ḥesed.
Psa. 89:3 can be made to appear to be saying that the first generations that kick-started mankind came about through incest.
