Ok, so I've been reading the Genisis story from the Message translation. Let me tell ya, it makes more sense then the King James version I grew up reading.
In chapter 4 Eve bares two sons; Cain and Able. Then Cain throws a temper tantrum and kills Able. In verse 15 God speaks to Cain's fear of being killed himself "'Anyone who kills Cain will pay for it seven times over.' GOD put a mark on Cain to protect him so that no one who met him would kill him."
Ok, according to what I've been taught, Adam and Eve were the first people. Cain and Able were the third and forth people. Now #3 has killed #4 leaving only 3 people. Here's my questions (you knew they were coming): Who is Cain afraid of? Would Eve kill Cain for killing Able? If he's just afraid of Adam-the only supposed person on the face of the Earth according to the teachers-wouldn't he have just said what if my father kills me instead of "whoever finds me" in verse 13?
Ok, so suppose Cain and Able have other brothers and sisters. We know that Cain is married, it says so in verse 17 when he sleeps with his wife. Is she his sister?
There's enough to get you started. Let me know your opinions and I'll finish sharing mine.
