Cain Married His Sister| Here Are the Reasons


We have well understood from the previous article Cain married his sister. The question the majority are asking is “Why he did do that?

This is because to them it is incest, and incest is an abominable act in the sight of God”. Well! that is quite true, but let us dive into some expositions.

He Formed Only Two

We read from the Holy Bible that God Created the world in Six (6) days and rested on the Seventh-Day-(Genesis 2:1-3).

And God climaxed His work of Creation by Forming Adam from the dust and Eve from his ribs.

And the Lord formed man of the dust of the ground, and breathed into his nostrils the breath of life, and man became a living being. Genesis 2:7 NKJV
And the LORD God caused a deep sleep to fall on Adam, and he slept; and He took one of his ribs, and closed up the flesh in its place. Then the rib which the LORD God had taken from man He made into a woman, and He brought her to the man. Genesis 2:21-22 NKJV

This means the LORD made only two People- Adam and Eve. so, the only people available for their sons to marry were their sisters.

This was not stated and mentioned, but we can logically conclude that Cain married his sister and they had children together because they were the only people existing then.

Did Cain Commit an incest by marrying his sister?

The answer is an award-winning No! In the unspoiled World of Eden before the Fall, God had not given them any law regarding marriage aside from this;

Therefore, a man shall leave his father and mother and be joined to his wife, and they shall become one flesh. Genesis 2:24 NKJV

This sound to reasoning Children and their Parents were the only “individuals” who were not to have sexual relations or marry each other!

So by Biblical standards, Cain was not breaking any law because nothing like incest existed at that time.

Adam and Eve Never Ate an Apple? |SEE DETAILS|

Aside from this, by our modern laws, Cain would have had to commit ‘incest’ with one of his sisters to bear children because he had no other choice.

God’s Law against incest?
God only commanded the people of Israel not to approach any of their relatives to uncover their nakedness after the Exodus(the Liberation of the people of Israel from Slavery in Egypt);
None of you shall approach anyone who is near of kin to him, to uncover his nakedness: I am the LORD. Leviticus 18:6 NKJV

Understand this, the regulations and the Laws of Moses bind those to whom it was given at that time.

So, this law was not working in the “Adamic era”. Meaning Cain was not subject to this law!

It is heart-warming to know that, the entire chapter 18 of Leviticus talks about the Laws regarding Sexual relations outlined for the people of Israel after their Exodus.


God formed only two people in the beginning, so the only people available for Cain to marry were his sisters.

Secondly, it was not an incest because there was no Law existing then to trash his act.

If we all are traced back to Adam and Eve, doesn’t it mean we are still marrying ourselves?
