And Cain went out from the presence of the LORD, and dwelt in the land of Nod, on the east of Eden. - Genesis 4:16
And Cain knew his wife; and she conceived, and bare Enoch: and he builded a city, and called the name of the city, after the name of his son, Enoch. - Genesis 4:17
But between verse 16 and verse 17, Cain met a woman. A woman whose eyes held the weight of the world and whose heart held an equally powerful grudge against Almighty God.
A woman named Lilith.
