A:  Actually verse 7 gives us a clue. Cain was really not trying to do what was right but just trying to get by. Verse 3 says that he merely brought some fruit as an offering while it says in verse 4 that Abel selected his offering the best fat portions from the first born of his flock. So on one hand there is an attitude difference.

Secondly, a blood sacrifice was what God instituted as an offering for sin. When Adam and Eve fell in the Garden God gave them the animal skins to wear. That was the first blood sacrifice for sin.

So in essence Cain was really starting his own religion here—the First Church of Fruit Sacrifice.

The blood sacrifice was an important feature of ancient religion instituted by God which was suppose to be a foreshadowing of the ultimate sacrifice of God’s own Son on the cross.

Were they not off spring of Adam/Eve, therefore brothers/sisters of Cain/Able?   -Chuck

A: Chuck, we actually dealt with that very question a couple of years ago. Here’s a link to the post:

“Who Was Cain Afraid Of?”

A: Genesis 4 contains the story of Cain & Abel. There is no progressive timeline presented here. The text jumps back & forth over perhaps 930 years from 4:1-5:5, and gives us only a few chosen events, names only 17 people, & references an undefined number of others.

The women born to Adam & Eve remain unnamed. Adam & Eve had many other sons & daughters, but only Abel, Cain, & Seth are named in the text. Cain & Abel are named because they are the first male children. Seth is named because he is the progenitor of the righteous, including Noah, Abraham, & latter Jesus (Luke 3:38).

The first women actually named in the text (besides Eve) are Adah & Zillah who marry Lamech, who is the great-great-great grandson of Cain. How many years have passed between the time of Cain & Lamech? Perhaps a minimum of 100 yrs, maybe 500-900 yrs. or more? The text does not give us their timeline. These people were living for around 900 years, they probably didn’t enter middle age till after 400, and could probably continue to have children for several hundred years. Cain has a wife, she was probably his sister, or maybe the daughter of Abel? Abel probably married a sister also. The text does not give us the specific answers or details. The text does say that Eve was the “Mother of all the living”–so all the folks were closely related. The genetic code was flawless at that point, later it would degenerate to the point that close relatives could no longer safely produce children. Here in Genesis, we can come up with hundreds of questions that the text does not fully deal with, or answer to our satisfaction.

Now to the question–The text does not have enough detail to give us a definitive answer. However, we can come to an informed conjecture:

First of all, it is quite probable that there were more people than just ‘Cain, Abel, Adam, & Eve’ at the time of the first murder. Close to 130 years had gone by (4:25, 5:3) since the beginning. Adam & Eve had many other children unnamed in the text. None of their daughters are named. Abel could well have had a family, and that family might have been quite large after 130 years. These are the folk that Cain was probably concerned about. Cain also could have been quite prolific in that time frame. After all, he is said to be building a city in the land of Nod, for his family & all those who presumably went with him. After all, if it is just Cain, his wife, & a new born son, there would be no need for a city. The human race could easily have numbered in the hundreds at the time of Abel’s murder. The text in question (4:14-15) itself and 4:17, really point to & support the view that there were already a substantial number of people living at the time of the first murder.
