Compare Genesis 2:8,”Then the Lord God planted a garden in the East, in a place called Eden. He put the man he had formed in that garden.” with Genesis 4:17,” Cain had intimate relations with his wife. She became pregnant and gave birth to Enoch. At that time Cain was building a city. He named it after his son Enoch.” Our Creator placed Adam in the garden and after Cain kills Able he went to build and live in a city. This indicates a slight negative idea of a city as a place where people live in a type of exile far away from the perfect garden that was free of sin.
