Holman Bible Dictionary
(cayin) Personal name meaning, “acquisition
.” The firstborn son of Adam and Eve (Genesis 4:1
). Although the meaning of the name is disputed, Eve's rationale for giving it suggests a relationship with a Hebrew root that means “to acquire.” Cain was a farmer, and his brother Abel was a shepherd. When the two men each brought an offering to the Lord, Abel's was accepted; but Cain's was not. Subsequently, Cain murdered Abel his brother. In punishment, God took from him the ability to till the ground productively and made him to be a wandering vagabond. God marked him off to protect him from anyone seeking to avenge Abel's murder.
