Where did Cain’s wife come from?

Where did Cain’s wife come from? This is the question many ask upon reading the story of Cain in Genesis 4, especially Genesis 4:17.

In the story of Genesis 4, Cain, after killing Abel, was sent away by God and he went to the land of Nod. After that, the story tells us that Cain had marital relations with his wife, and his wife became pregnant and gave birth to Enoch. The story, however, never tells us where Cain’s wife came from; it doesn’t directly give us her identity. Thus, assumptions are made by many.

But assumptions are not what we should be after if we wish to respect the context of the written Word of God. In fact, the Word of God is clear that Adam’s race is the only human race that has existed throughout the whole history of this universe. Therefore, Cain’s wife was from Adam’s race, not from some other [imaginary] human race.

This leads us to questions, though. For example, where does the Bible say that Adam’s race is the only human race that has ever existed?

Acts 17:26:
From one man he made every nation of men, that they should inhabit the whole earth; and he determined the times set for them and the exact places where they should live.

So the Bible clearly says that he made all humans from one man (one blood). Who is this one man? Adam!

And for confirmation, Genesis 3:20 says:
Adam named his wife Eve, because she would become the mother of all the living.

So Eve is the mother of all humans, as she is the wife of the father of all humans, Adam.

And for yet another confirmation, here’s what Romans 5:12-14 says:
Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned—for before the law was given, sin was in the world. But sin is not taken into account when there is no law. Nevertheless, death reigned from the time of Adam to the time of Moses, even over those who did not sin by breaking a command, as did Adam, who was a pattern of the one to come.

What is the passage saying? It is saying that death reigned over all humans, even those who did not sin by breaking any command (such as babies). How come? Because, just as the passage states, death entered the world because of the sin of Adam, and, as all humans are in Adam (as all humans inherit Adam’s nature), all humans experience death because of the sin of the head of the human race, Adam.

1 Corinthians 15:21-22
For since death came through a man, the resurrection of the dead comes also through a man. For as in Adam all die, so in Christ all will be made alive.

As all humans experience death, all humans are [originally] in Adam => all humans are descendants of Adam [and Eve].

And that is why the Bible says that all have sinned (Romans 3:23). Every human out there is in need of Jesus, the Savior, as all humans share the same corrupted nature. For more details on why Jesus is the only way for you to be saved, go here.

Thus, we see that the Bible clearly says that all humans are descendants of Adam and Eve. Therefore, Cain’s wife was one of them.

After hearing this, the next matter someone would most likely wonder about is the following:

If Cain’s wife was from Adam’s race, does this mean she was Cain’s sister or something? Isn’t this incest? I thought God was against incest! How could He allow them to sin by committing incest?

The answer is simple. In the days of Cain, marrying your sister (or niece) was not yet a violation of God’s law, for there was nothing wrong with such a thing back then.

Yes, you heard me right. There was nothing wrong with marrying your sister back then!

You see, God’s law is not for show. Every commandment that comes from God is for a good divine reason. A man marrying his sister did not lead to severe biological deformities and genetic diseases in their children back then (as it so happens today).

Adam and Eve, for example, were born perfect, and the genetic makeup of each was perfect compared to that of today’s human, for they were created before sin ever came, biologically and spiritually corrupting our human nature. While today’s human is born long after the fall which has already affected us in many negative ways.

Back then, even right after the fall, there was not much deformities and diseases and imperfections as there are today, as the negative effects of the fall have been quite slow and gradual. I mean, it took a while for AIDS to emerge; it was only recently that AIDS has become a threat to us. And, of course, there are other examples of diseases that have emerged only recently.

So, it was much safer for the humans back then to marry their siblings, as it was not likely that such unions would lead to severe genetic diseases in the children they bore, due to the fact that the gradual effects of the fall were still in the beginning stages.

Actually, the Bible mentions how the humans back then (in Genesis) lived long, long lives (around 900 years of age!). And it shows us how the human’s average life span gradually diminished from around 900 years to around 150 years of age, and now it’s around 80-90 years of age. All due to the gradual effects of the fall.

This is why marrying your sister (or niece) was not a violation of God’s law back then, as there was no harm to it and as it was necessary for the initial increase of the human population!

It was only until the days of Moses that such acts have become a sin. Abraham, for example, married Sarah, who was his half sister!

Read what Abraham says about his wife in Genesis 20:12:
Besides, she really is my sister, the daughter of my father though not of my mother; and she became my wife.

Today (due to the effects of the fall), according to the law of God, it’s a sin to marry your half sister, your sister, your niece, and your aunt. And of course, it’s a sin to marry your mother and your daughter. For if you love your neighbor as yourself, you will not marry your sister and have sexual relations with her today.

Now we know that Cain’s wife was from Adam’s human race (whether as Cain’s sister or a niece of his, we don’t know) and that it was not a sin for Cain to marry her and have sexual relations with her.

The next question one might ask is: Does the Bible even mention daughters of Adam that Cain could pick from and choose as his wife?

For sure! Genesis 5:4 says that Adam had daughters! So it would not have been impossible for Cain to pick a wife from among his father’s daughters.

We don’t know the names and the details of Adam’s daughters, but we do know that he had daughters, because the Bible says so clearly.

In conclusion, the question about the identity of Cain’s wife has been answered according to the truth of God’s word.

One Response to Where did Cain’s wife come from?

  1. Indeed, brother, the Bible is clear about these matters.

    It is to be noted that the Bible never forbids you to marry your sister from Adam, or else you would not be permitted to be married!! Yes, indeed, many do not get this point and find it ridiculous, but when we really understand it in its real sense, we will see that this is very right, and not even the Law has forbidden marrying your sister from Adam. And the Bible never says that marrying your sister from Adam is incest!! I wonder where do people ever read that?? Marrying your sister from Adam is NOT incest. Actually, there is no way that you marry any girl but a daughter of Adam! Look around you; you see all those people? They all are the children of Adam and your brothers and sisters from Adam! So when you marry a girl, you’re surely marrying your sister from Adam. If you don’t believe this, then you don’t believe that just as the Bible says God made us all from one man, Adam.

    But what did the Law really forbid? And did it forbid something that was not sin before?

    Well, the Law of God is eternal! The standard of God’s Holiness did never change. What God says is a sin was always a sin! But actually, we need to understand what the Law really says. It doesn’t say that you should not marry your sister POINT. It explains why. And indeed, you explained, in the language of today’s culture, why God has forbidden us to marry any of our close relatives. And the explanation is right. During time, the results of the Fall increased, and mutation after mutation, we now have a genome that is full of mutations among which many are hidden and that will appear as soon as you marry anyone from your close relatives. Anyone who has a basic knowledge about genetics and biology knows very well that recessive alleles are found in our genome. A recessive allele is one of a pair of alternative alleles whose effect is masked by the activity of the second when both are present in the same cell or organism. So the dominant allele will give you an outward character that does not show the effect of that recessive allele. But if another person has the same recessive allele and you both get married, your child will have two of the same recessive alleles and then the character of that recessive allele will appear on him. Suppose that this recessive allele codes for a big genetic disease, and you will know what the child will have! He will have that big genetic disease! So you will have a child who will suffer all his life because you did something you KNEW would make that recessive allele appear! And many, if not all of those genetic diseases forbid humans from getting married for different reasons. Now imagine how much God would be cruel if He allowed such marriages after so much mutations happened in the human genome! He would be contradicting Himself! For God from the beginning wanted us to be fruitful and to fill the earth. If He allows something like this, He will be allowing the exact opposite of what He wants and of what is good.

    Now, all this was how the modern man of science explains the same thing that the Bible explains but with other terms, the terms that all men in all cultures at that time could understand. Besides, the terms that the science man uses are only materialistic, while the terms of the Bible go deeper into the moral meaning. Let’s see how.

    First, let me make it clear that marrying your mother was always a sin. Jesus, who alone as God has the right to interpret the Scripture, explained to us that your mother is one flesh with your father, so it is a sin, and a big sin, even to think about anything that violates this truth. Even the children of Adam would sin a big sin if they even turned their eyes toward their mother, Eve. And we thank God that He didn’t allow this big sin to happen with Eve! And indeed the Law agrees with this when it says clearly:

    “The nakedness of thy father, and the nakedness of thy mother, shalt thou not uncover: she is thy mother: thou shalt not uncover her nakedness.” (Leviticus 18:7)

    If you uncover the nakedness of your mother, you’re uncovering the nakedness of your father!! She’s ONE FLESH with your father! That’s the worst kind of adultery and incest and immorality!! A child of God would not even dare to think about it! And we say it here with big disgust!

    But the Law goes further than this and clarifies that the genetic problem has nothing to do with the matter of your parents. Marrying one of your parents is out of question even if he/she is not your real father/mother! Why? Again, because they are one flesh:

    “The nakedness of thy father’s wife shalt thou not uncover: it is thy father’s nakedness.” (Leviticus 18:8)

    Clear! And this was true since the beginning.

    Now, concerning your relatives from Adam, you read nowhere in the Bible that you should not marry one of your sisters from Adam. But you read that you should not marry one of your relatives from your direct parents! Adam was not the direct parent of anyone when the Law was given. As we saw above, it was not wrong for the direct children of Adam to marry each other, as there was not the problem of mutations and diseases. But in the time of Moses, there was! And today also there is! And this is what the Law explains when it talks about why you should not marry any of your relatives:

    “The nakedness of thy sister, the daughter of thy father, or daughter of thy mother, born at home, or born abroad — their nakedness shalt thou not uncover.” (Leviticus 18:9)

    The Law talks about the daughter of YOUR father or the daughter of YOUR mother, and not the daughter of ANY of your first parents, Adam and Eve! God has no problem with you marrying a daughter of your first parents. He has a problem with you marrying the daughter of YOUR direct father or mother. Why? Well, we have seen the scientific explanation. While the Bible gives you the moral explanation which is that any of your relatives has a close physical relation with you, and you should not disrespect that. You should not disrespect the flesh of your parents.


    “The nakedness of thy son’s daughter, or of thy daughter’s daughter — their nakedness shalt thou not uncover; for theirs is thy nakedness.” (Leviticus 18:10)

    You see the relation? Whenever it’s a close relation with your body or the body of any parent, you are forbidden to marry him/her.

    “The nakedness of thy father’s wife’s daughter, begotten of thy father: she is thy sister: thou shalt not uncover her nakedness.” (Leviticus 18:11)

    Why? Because your father and his wife (even if she’s not your real mother) are ONE FLESH.


    So we see that it was always morally wrong to marry the daughter of your parents, as long as there was a physical and/or a fleshly problem in doing that! But it was never a sin to marry a daughter of Adam and Eve! Nowhere does the Bible say that it’s a sin or incest to marry a daughter of Adam and Eve. Actually, no human has ever married a daughter of anyone but Adam.

    Just like Cain and Seth (the child who was born as offspring in the place of Abel who was killed — see Genesis 4:25), we all marry a daughter of Adam. And we all have the same sinful nature of Adam. Only Jesus Christ didn’t have that sinful nature of Adam, as He was born of a virgin, just as God planned. Only Jesus can save us from all sins, as SoldierofChrist explained in the original post.

    Finally, before I close this reply, let me turn your attention to something interesting: As the wife of Cain was one of his relatives, and most probably his sister, one would not expect her to marry Cain after he killed her brother or relative and was now cursed and would be a vagrant and a wanderer on the earth (see Genesis 4:11-12). And the Bible never tells us about Cain taking a wife in marriage, but it introduces the wife of Cain directly in marital relations already in Genesis 4:17. This makes us understand that Cain was already married when he killed his brother.

    Now think how hard it was for this sister of Abel to live with the murderer of her brother, the first murderer in the history of humanity!

    Maybe we should make the question a more compassionate one! “Who was the wife of Cain?” “What kind of woman she was?” “Did she marry a murderer who she knew was a murderer?” “Did she find herself obliged to live with a man who she knew was a murderer?” “Was she like him? Was she pleased with what he did?”…

    Many compassionate and moral questions can be asked here. While all what people care about is to oppose the Word of God without understanding what it really says!

    Grace be with you!
    Disciple of Jesus Christ
