Life as recorded in the Bible
Cain (Hebrew, "acquisition") was the firstborn son of Adam and Eve as recorded in the Bible. Born after the fall, he became a farmer. He was the first murderer, killing his brother Abel because God accepted Abel's offering, but not Cain's. God punished him by cursing him to be a wanderer who would always have to toil hard for little reward. When Cain protested that "whoever finds me will kill me," God put a mark on him so that "if anyone kills Cain, he will suffer vengeance seven times over."
