The eldest son of Cain (Gen. 4:17), who built a city east of Eden in the land of Nod, and called it “after the name of his son Enoch.” This is the first “city” mentioned in Scripture.
Gen.4: 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.
