Curse of Cain
The Curse of Cain and the mark of Cain are phrases that originated in the story of Adam and Eve in the Hebrew Bible. In the stories, if someone did something to harm Cain, the damage would come back sevenfold. Some interpretations view this as a physical mark, whereas other interpretations see the "mark" as a sign, and not as a physical mark on Cain himself. The King James Version of the Bible reads "set a mark upon Cain." [1]
