Can you please be more specific? What verse, word etc is giving that implication to you? I am asking this because it reminds me one of Quran's verses about Noah and his son (
11:46). It says "He is not of your family". Noah thinks he is his son, but he is actually not his son, he is not of his family.
Genesis 5, from the Peshitta:
"
1This is the scroll of the generations of Adam in the day that God created Adam; He created him in the form of God;
2Male and female He created them and God blessed them and he called their name Adam in the day that he created them.
3And Adam lived a hundred and thirty years, and he begot in his likeness, according to his image, and he called his name Shayth: 4And Adam lived eight hundred years after he begot Shayth, and he begot sons and daughters: 5And all the days that Adam lived were nine hundred and thirty years, and he died.
6And Shayth lived a hundred and five years, and he begot Enosh:
7And Shayth lived from after he begot Enosh, eight hundred and seven years, and he begot sons and daughters:
8And all the days of Shayth were nine hundred and twelve years, and he died.
9And Enosh lived ninety years and he begot Qaynan:
10And Enosh lived after he begot Qaynan, eight hundred and fifteen years, and he begot sons and daughters:
11And all his days of Enosh were nine hundred and five years, and he died.
12And Qaynan lived seventy years and he begot Mehalaleil:
13And Qaynan lived after he begot Mehalaleil, eight hundred and forty years, and he begot sons and daughters:
14And all the days of Qaynan were nine hundred and ten years, and he died.
15And Mehalaleil lived sixty and five years and begot Yared:
16And Mehalaleil lived after he begot Yared, eight hundred and thirty years, and he begot sons and daughters:
17And all the days of Mehalaleil were eight hundred and ninety and five years, and he died.
18And Yared lived a hundred and sixty and two years, and he begot Khenok:
19And Yared lived after he begot Khenok, eight hundred years, and begot sons and daughters:
20And all the days of Yared were nine hundred and sixty and two years, and he died.
21And Khenok lived sixty and five years and begot Methushelakh:
22And Khenok was pleasing to God, after he begot Methushelakh, three hundred years, and he begot sons and daughters:
23And all the days of Khenok were three hundred and sixty and five years.
24And Khenok pleased God, and he was not, because God took him.
25And Methushelakh lived a hundred and eighty and seven years and begot Lamek:
26And Methushelakh lived, after he begot Lamek, seven hundred and eighty and two years, and he begot sons and daughters:
27And all the days of Methushelakh were nine hundred and sixty and nine years, and he died.
28And Lamek lived two hundred years and begot a son:
29And he called his name Noah, and said, “This one will comfort us from our works, and from the labor of our hands, and from the Earth which LORD JEHOVAH cursed.”
30And Lamek lived, after he begot Noah, five hundred and ninety and five years, and begot sons and daughters:
31And all the days of Lamek were seven hundred and seventy and seven years, and he died.
32And Noah was a son of five hundred years, and Noah begot Shym and Kham and Yapheth."
Genesis chapter 5 is the genealogy of Adam through to Noah. Cain is not listed as one of Adam's sons. No doubt because righteous Abel died an untimely death is likely why he is not included. An argument perhaps could be made that Cain was disowned. I think a deeper reading of Genesis 4 would show that Eve "continued in labor," that Cain and Abel were twins by different Fathers. (It is medically possible.) I realize not all Christians are in agreement with this point, nevertheless Cain is not included in the genealogy of Adam.
