The general question of where Cain, the son of Adam, got his wife from is asked by a lot of ignorant or contentious people.
Years ago I remember “Father” Jonathan Morris, a highly ranked Catholic priest, being asked this question on Fox News. He could not answer it because the Catholic Church does not encourage the Whore’s sons to study the Bible. Morris was stumped said he would ask the Pope about that and I never saw any follow up on Fox News nor in writing thereafter.
The answer is plainly in the Bible. The Bible says Adam had sons AND daughters and it says that after he had three named sons so those were additional children beyond his official line of succession. And so we know Adam had sons not listed by name in the genealogies of his descendants and none of his daughters were listed by name, but we know he had them. That means he could have had sons and daughters before that which were not listed in the genealogies before Cain chose a wife which means that even if he had no other sons except the three named in the genealogies before those additional ones he could have had at least daughters from which Cain to chose a wife.
Adam lived a total of nine hundred and thirty years and so had that many years in order to bear children. Eve being the mother of all living would have birthed all those children and assuming gestation was the same then since one child can be born each year with three months of weening before the next beside the possibility of twins, etc. and Adam had Seth when Adam was one hundred and thirty years old and sons and daughters were still being born after that we can estimate that Eve had about nine hundred to nine hundred and fifty children in total. We can assume she bore a lot of children because God told her and Adam to be fruitful and multiply; not to simply add to the population by a small number.
Since demographics show consistently that male to female ratios of births affecting populations remain almost exactly a fifty-fifty ratio within a margin of a few percentage points (men being usually slightly less in older populations and women slightly less by birth but which are adjusted for to average out. Note: Wars and work and healthcare neglect harm men disproportionately causing their lifespans to be shorter.) we can assume that Eve could have had about four hundred and fifty daughters before Adam’s death.
When we consider that Cain took a wife earlier in history than when Seth was born and the verses say, “And Lamech said unto his wives, Adah and Zillah, Hear my voice; ye wives of Lamech, hearken unto my speech: for I have slain a man to my wounding, and a young man to my hurt. 24 If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold. And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew.” we start to see that the Bible may be implying that Cain’s bloodline died off before Noah’s flood, like Abel’s may have due to his murder by Cain (although it is not clear if Abel had any descendants or not).
From the text we know that Cain was the first born of Eve, at least listed by name, and probably the first in fact, but he did not slay his brother until after a “process of time it came to pass” and Cain is specifically said to have his own children until after that and so there would have been plenty of women to choose from by that time from Adam’s daughters, which would have been Cain’s sisters. Cain could have had more than one wife, but this is only a possibility and the text implies he only had one and this may have led to his bloodline being wiped out when Lamech killed a young man to his “own hurt”, which may imply that he killed his own son, Tubalcain, which may explain why Lamech’s son, Tubalcain, was said to have a sister (Naamah) listed specifically by name, a listing of a sister’s name a bit rare in the genealogies, for in the absence of a male heir females can inherit property from their fathers. “Genesis 5:22 And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah. ” This would make some sense as Cain was to be avenged seven-fold for killing a brother, but Lamech was to be avenged seventy and sevenfold for perhaps killing his own close relative, perhaps even his son. For…
“Matthew 18:21 Then came Peter to him, and said, Lord, how oft shall my brother sin against me, and I forgive him? till seven times?
22 Jesus saith unto him, I say not unto thee, Until seven times: but, Until seventy times seven.” Jesus being the Son of God slain would have more forgiveness afforded to his brethren than for a brother slain.
Lamech had two wives (Lamech “took unto him two wives.”). Cain is said to have “his wife” and so Cain, like his father must have had only one wife, at least only one at the time being spoken of, from which was born his son Enoch.
Abel too may have had daughters but of which none are specifically listed and he may had no children as none are listed. And I think it may be incorrect to assume that Abel had heirs for Cain and Abel’s story like that of Lamech’s appears to imply an end a bloodline, but this is at best implied and not explicit. But in any case only Enoch’s bloodline survived the flood of Noah with Cain and Abel’s bloodline not, but it is possible some of Enoch’s family mixed with that of Cain’s or Abels, if Abel had any, but this may not be the case for the text seems to imply that Seth was God’s gift to Eve to replace the bloodline lost by the death of Abel and Seth was explicitly a replacement for Abel himself as God’s gift to Eve and Eve is not said to have had Seth until after Lamech slain a young man to his own hurt and so that implies that both Abel’s and Cain’s bloodline was lost from the human race, at least through male heirs and Seth began the line of succession from Adam anew.
And so we can see that there were plenty of women from which Cain could have chosen himself a wife. Either from the daughters of Adam, (Cain’s sisters) or from the daughters of Abel if he had any.
The prohibition against marrying close relatives was not put into place until Leviticus chapter eighteen and so Cain marrying his sister or his brother’s daughter would have been permissible in this early period of history when the human race was first starting, but is something no longer permitted under the law of God since God gave the commandments to Moses.
The fact a Catholic priest, trained to be a personal advisor to the Pope in Rome, can not answer a simple question like this speaks volumes about the ignorance of the Babylonian Whore’s membership.
Genesis 4:1 And Adam knew Eve his wife; and she conceived, and bare Cain, and said, I have gotten a man from the LORD.
2 And she again bare his brother Abel. And Abel was a keeper of sheep, but Cain was a tiller of the ground.
3 And in process of time it came to pass, that Cain brought of the fruit of the ground an offering unto the LORD.
4 And Abel, he also brought of the firstlings of his flock and of the fat thereof. And the LORD had respect unto Abel and to his offering:
5 But unto Cain and to his offering he had not respect. And Cain was very wroth, and his countenance fell.
6 And the LORD said unto Cain, Why art thou wroth? and why is thy countenance fallen?
7 If thou doest well, shalt thou not be accepted? and if thou doest not well, sin lieth at the door. And unto thee shall be his desire, and thou shalt rule over him.
8 And Cain talked with Abel his brother: and it came to pass, when they were in the field, that Cain rose up against Abel his brother, and slew him.
9 And the LORD said unto Cain, Where is Abel thy brother? And he said, I know not: Am I my brother’s keeper?
10 And he said, What hast thou done? the voice of thy brother’s blood crieth unto me from the ground.
11 And now art thou cursed from the earth, which hath opened her mouth to receive thy brother’s blood from thy hand;
12 When thou tillest the ground, it shall not henceforth yield unto thee her strength; a fugitive and a vagabond shalt thou be in the earth.
13 And Cain said unto the LORD, My punishment is greater than I can bear.
14 Behold, thou hast driven me out this day from the face of the earth; and from thy face shall I be hid; and I shall be a fugitive and a vagabond in the earth; and it shall come to pass, that every one that findeth me shall slay me.
15 And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.
16 And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden.
17 And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch.
18 And unto Enoch was born Irad: and Irad begat Mehujael: and Mehujael begat Methusael: and Methusael begat Lamech.
19 And Lamech took unto him two wives: the name of the one was Adah, and the name of the other Zillah.
20 And Adah bare Jabal: he was the father of such as dwell in tents, and of such as have cattle.
21 And his brother’s name was Jubal: he was the father of all such as handle the harp and organ.
22 And Zillah, she also bare Tubalcain, an instructer of every artificer in brass and iron: and the sister of Tubalcain was Naamah.
23 And Lamech said unto his wives, Adah and Zillah, Hear my voice; ye wives of Lamech, hearken unto my speech: for I have slain a man to my wounding, and a young man to my hurt.
24 If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold.
25 And Adam knew his wife again; and she bare a son, and called his name Seth: For God, said she, hath appointed me another seed instead of Abel, whom Cain slew.
26 And to Seth, to him also there was born a son; and he called his name Enos: then began men to call upon the name of the LORD.
Genesis 5:1 This is the book of the generations of Adam. In the day that God created man, in the likeness of God made he him;
2 Male and female created he them; and blessed them, and called their name Adam, in the day when they were created.
3 And Adam lived an hundred and thirty years, and begat a son in his own likeness, after his image; and called his name Seth:
4 And the days of Adam after he had begotten Seth were eight hundred years: and he begat sons and daughters:
5 And all the days that Adam lived were nine hundred and thirty years: and he died.
Numbers 27:1 Then came the daughters of Zelophehad, the son of Hepher, the son of Gilead, the son of Machir, the son of Manasseh, of the families of Manasseh the son of Joseph: and these are the names of his daughters; Mahlah, Noah, and Hoglah, and Milcah, and Tirzah.
2 And they stood before Moses, and before Eleazar the priest, and before the princes and all the congregation, by the door of the tabernacle of the congregation, saying,
3 Our father died in the wilderness, and he was not in the company of them that gathered themselves together against the LORD in the company of Korah; but died in his own sin, and had no sons.
4 Why should the name of our father be done away from among his family, because he hath no son? Give unto us therefore a possession among the brethren of our father.
5 And Moses brought their cause before the LORD.
6 And the LORD spake unto Moses, saying,
7 The daughters of Zelophehad speak right: thou shalt surely give them a possession of an inheritance among their father’s brethren; and thou shalt cause the inheritance of their father to pass unto them.
8 And thou shalt speak unto the children of Israel, saying, If a man die, and have no son, then ye shall cause his inheritance to pass unto his daughter.
9 And if he have no daughter, then ye shall give his inheritance unto his brethren.
10 And if he have no brethren, then ye shall give his inheritance unto his father’s brethren.
11 And if his father have no brethren, then ye shall give his inheritance unto his kinsman that is next to him of his family, and he shall possess it: and it shall be unto the children of Israel a statute of judgment, as the LORD commanded Moses.
Genesis 20:1 And Abraham journeyed from thence toward the south country, and dwelled between Kadesh and Shur, and sojourned in Gerar.
2 And Abraham said of Sarah his wife, She is my sister: and Abimelech king of Gerar sent, and took Sarah.
3 But God came to Abimelech in a dream by night, and said to him, Behold, thou art but a dead man, for the woman which thou hast taken; for she is a man’s wife.
4 But Abimelech had not come near her: and he said, Lord, wilt thou slay also a righteous nation?
5 Said he not unto me, She is my sister? and she, even she herself said, He is my brother: in the integrity of my heart and innocency of my hands have I done this.
6 And God said unto him in a dream, Yea, I know that thou didst this in the integrity of thy heart; for I also withheld thee from sinning against me: therefore suffered I thee not to touch her.
7 Now therefore restore the man his wife; for he is a prophet, and he shall pray for thee, and thou shalt live: and if thou restore her not, know thou that thou shalt surely die, thou, and all that are thine.
8 Therefore Abimelech rose early in the morning, and called all his servants, and told all these things in their ears: and the men were sore afraid.
9 Then Abimelech called Abraham, and said unto him, What hast thou done unto us? and what have I offended thee, that thou hast brought on me and on my kingdom a great sin? thou hast done deeds unto me that ought not to be done.
10 And Abimelech said unto Abraham, What sawest thou, that thou hast done this thing?
11 And Abraham said, Because I thought, Surely the fear of God is not in this place; and they will slay me for my wife’s sake.
12 And yet indeed she is my sister; she is the daughter of my father, but not the daughter of my mother; and she became my wife.
13 And it came to pass, when God caused me to wander from my father’s house, that I said unto her, This is thy kindness which thou shalt shew unto me; at every place whither we shall come, say of me, He is my brother.
Exodus 6:20 And Amram took him Jochebed his father’s sister to wife; and she bare him Aaron and Moses: and the years of the life of Amram were an hundred and thirty and seven years.
Leviticus 18:1 And the LORD spake unto Moses, saying,
2 Speak unto the children of Israel, and say unto them, I am the LORD your God.
3 After the doings of the land of Egypt, wherein ye dwelt, shall ye not do: and after the doings of the land of Canaan, whither I bring you, shall ye not do: neither shall ye walk in their ordinances.
4 Ye shall do my judgments, and keep mine ordinances, to walk therein: I am the LORD your God.
5 Ye shall therefore keep my statutes, and my judgments: which if a man do, he shall live in them: I am the LORD.
6 None of you shall approach to any that is near of kin to him, to uncover their nakedness: I am the LORD.
7 The nakedness of thy father, or the nakedness of thy mother, shalt thou not uncover: she is thy mother; thou shalt not uncover her nakedness.
8 The nakedness of thy father’s wife shalt thou not uncover: it is thy father’s nakedness.
9 The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, whether she be born at home, or born abroad, even their nakedness thou shalt not uncover.
10 The nakedness of thy son’s daughter, or of thy daughter’s daughter, even their nakedness thou shalt not uncover: for theirs is thine own nakedness.
11 The nakedness of thy father’s wife’s daughter, begotten of thy father, she is thy sister, thou shalt not uncover her nakedness.
12 Thou shalt not uncover the nakedness of thy father’s sister: she is thy father’s near kinswoman.
13 Thou shalt not uncover the nakedness of thy mother’s sister: for she is thy mother’s near kinswoman.
14 Thou shalt not uncover the nakedness of thy father’s brother, thou shalt not approach to his wife: she is thine aunt.
15 Thou shalt not uncover the nakedness of thy daughter in law: she is thy son’s wife; thou shalt not uncover her nakedness.
16 Thou shalt not uncover the nakedness of thy brother’s wife: it is thy brother’s nakedness.
17 Thou shalt not uncover the nakedness of a woman and her daughter, neither shalt thou take her son’s daughter, or her daughter’s daughter, to uncover her nakedness; for they are her near kinswomen: it is wickedness.
18 Neither shalt thou take a wife to her sister, to vex her, to uncover her nakedness, beside the other in her life time.
Genesis 3:1 Now the serpent was more subtil than any beast of the field which the LORD God had made. And he said unto the woman, Yea, hath God said, Ye shall not eat of every tree of the garden?
2 And the woman said unto the serpent, We may eat of the fruit of the trees of the garden:
3 But of the fruit of the tree which is in the midst of the garden, God hath said, Ye shall not eat of it, neither shall ye touch it, lest ye die.
4 And the serpent said unto the woman, Ye shall not surely die:
5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
6 And when the woman saw that the tree was good for food, and that it was pleasant to the eyes, and a tree to be desired to make one wise, she took of the fruit thereof, and did eat, and gave also unto her husband with her; and he did eat.
7 And the eyes of them both were opened, and they knew that they were naked; and they sewed fig leaves together, and made themselves aprons.
8 And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden.
9 And the LORD God called unto Adam, and said unto him, Where art thou?
10 And he said, I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself.
11 And he said, Who told thee that thou wast naked? Hast thou eaten of the tree, whereof I commanded thee that thou shouldest not eat?
12 And the man said, The woman whom thou gavest to be with me, she gave me of the tree, and I did eat.
13 And the LORD God said unto the woman, What is this that thou hast done? And the woman said, The serpent beguiled me, and I did eat.
14 And the LORD God said unto the serpent, Because thou hast done this, thou art cursed above all cattle, and above every beast of the field; upon thy belly shalt thou go, and dust shalt thou eat all the days of thy life:
15 And I will put enmity between thee and the woman, and between thy seed and her seed; it shall bruise thy head, and thou shalt bruise his heel.
16 Unto the woman he said, I will greatly multiply thy sorrow and thy conception; in sorrow thou shalt bring forth children; and thy desire shall be to thy husband, and he shall rule over thee.
17 And unto Adam he said, Because thou hast hearkened unto the voice of thy wife, and hast eaten of the tree, of which I commanded thee, saying, Thou shalt not eat of it: cursed is the ground for thy sake; in sorrow shalt thou eat of it all the days of thy life;
18 Thorns also and thistles shall it bring forth to thee; and thou shalt eat the herb of the field;
19 In the sweat of thy face shalt thou eat bread, till thou return unto the ground; for out of it wast thou taken: for dust thou art, and unto dust shalt thou return.
20 And Adam called his wife’s name Eve; because she was the mother of all living.
