In this case though, the innocent victim (Abel) represents the storytellers while the killer (Cain) represents the city-people and settled farmers who were their hereditary adversaries. This theme recurs throughout the Hebrew Bible. The future patriarch Abram (later called Abraham) leaves the Mesopotamian city Ur with his wife Sarai (later Sarah) and wanders through Canaan and Egypt before settling in what is now Palestine.
As someone who reads their bible constantly, I appreciate this in here! It is something I am knowledgeable about and makes everything feel less overwhelming.
