I am reading my way through the Old Testament but finding the many cases of incest really very disturbing. Why on earth was it so prevalent?
We naturally feel horror at the very thought of such relationships between close family, even more distant family. Every culture abhors and bans it, rightly. The greatest taboo.
So why on earth did such significant figures in the Bible do it? They specifically looked for close relations for marriage with their children. I do find it very off putting!
It only became incest when God handed down the law in the time of Moses. Before this, there was no law and I also believe no feeling of wrongness. God determines what is right and wrong so since he did not find it wrong I also believe that inner feeling of repugnance we have towards it also did not came into being until then. This meant marriage not other types of sexual behavior that was frowned upon.
Where did Cain get his wife? This is a question because people want there to be some other people, but there was not.
1 Corinthians:15-22
For as in Adam all die, so in Christ all will be made alive.
If we came from some other person or group we would not be included. We all sin and we all need Christ because we all come from Adam.
Genesis:3-20
Adam named his wife Eve, because she would become the mother of all the living.
Not some or a group, but all.
Cain's wife was his sister as were the other couples.
They lived a long time and would have all had many children, so very quickly there was no need for close family connections.
Abraham was married to his half-sister Sarah and God did not frown upon this but made sure they had a child.
Genesis: 20-12
Besides, she really is my sister, the daughter of my father though not of my mother; and she became my wife.
17 Abraham fell facedown; he laughed and said to himself, “Will a son be born to a man a hundred years old? Will Sarah bear a child at the age of ninety?” 18 And Abraham said to God, “If only Ishmael might live under your blessing!”
19 Then God said, “Yes, but your wife Sarah will bear you a son, and you will call him Isaac. I will establish my covenant with him as an everlasting covenant for his descendants after him.
Leviticus 18:8-18 God gives them a long list of who they should not have relations with. Listing 9 family members.
