Biblical Antiquities (Pseudo-Philo) 2
2And Cain knew Themech his wife and she conceived and bare Enoch.
3Now Cain was 15 years old when he did these things; and from that time he began to build cities, until he had founded seven cities. And these are the names of the cities: The name of the first city according to the name of his son Enoch. The name of the second city Mauli, and of the third Leeth, and the name of the fourth Teze, and the name of the fifth Jesca; the name of the sixth Celeth, and the name of the seventh Jebbath.
4And Cain lived after he begat Enoch 715 years and begat 3 sons and 2 daughters. And these are the names of his sons: Olad, Lizaph, Fosal; and of his daughters, Citha and Maac. And all the days of Cain were 730 years, and he died.
6But Lamech took unto himself two wives: the name of the one was Ada and the name of the other Sella.
10Now Lamech said unto his two wives Ada and Sella: Hear my voice, ye wives of Lamech, give heed to my precept: for I have corrupted men for myself, and have taken away sucklings from the breasts, that I might show my sons how to work evil, and the inhabiters of the earth. And now shall vengeance be taken seven times of Cain, but of Lamech seventy times seven.
