In both the LORD asks where people are (3:9; 4:9)
In both the LORD asks what people have done (3:13; 4:10)
In both there is a curse on the relationship of people with the ground (3:17; 4:11)
In both people are driven from the presence of God (3:24; 4:14)
In both people end up heading east from Eden (3:24; 4:16)
In both God provides a mark/covering for those he has driven out (3:21; 4:15)
At the end of both a new child is born to Eve (4:1; 4:25)
...history will only continue to repeat itself until the promised Seed is born.
