Cain was the first farmer, the first murderer, and the first city-dweller. Annoyed because h is brother Abel's offering was more acceptable to God, Cain killed Abel. He tried to hide hi s guilt, but could not, and was forced to face up to God for what he had done.Condemned to b e a restless wanderer, Cain built the first city, Enoch.(Everyone in the Bible, by William P . Barker, 1966)
