"Then Cain went out from the presence of the Lord, and settled in the land of Nod, east of Eden. And Cain had relations with his wife and she conceived, and gave birth to Enoch; and he built a city, and called the name of the city Enoch, after the name of his son," (Genesis 4:17)

I have two questions

1. From where did Cain get his wife from? Was there any other race made by God apart from Adam?
   
2. If Cain married his sister (as this is general belief) does it not come in Incest?

Where did Adam get his wife from?

"Then the days of Adam after he became the father of Seth were eight hundred years, and he had other sons and daughters." (Genesis 5:4)

Cain married one of his sisters. It was not incest as the Law came quite late, No one is to approach any close relative to have sexual relations. I am the LORD," (Lev. 18:6)

Therefore keeping in mind that there was no race other than Adam and Eve, Cain married his own sister. As Bible never mentions another human than Adam and Eve, so there is no point in discussing this. Jesus came to earth to redeem Adam, Eve and their descendants.

Thank you for your answer and I agree with you that Cain married his own sister. What about the incest part? Please comment on that using a verse from the Bible. Thanks in adavnce.

Hear, O Israel, the decrees and laws I declare to you today. Learn them and be sure to follow them. The LORD our God made a covenant with us at Horeb. It was not with our fathers that the LORD made this covenant, but with all of us who are alive here today. (Deuteronomy 5:1-5)

This statement of the Moses clearly says that Abraham, Isaac, Jacob and all those who were before them were not under these decrees and laws. I hope I have answered your question.

God bless you

Thank you I have understood it now. Blessings in Jesus
