On the Posterity of Cain and his Exile
[40] Now since Cain is said to have begotten Enoch, and there is afterwards a descendant of Seth with the name of Enoch again (Gen. 4:17, 5:18), we must consider whether they were two different persons or the same person. While we are engaged with these, let us investigate also the difference between others who have the same name. Like Enoch, Methuselah and Lamech appear as descendants of Cain, and descendants no less of Seth (Gen. 4:18, 5:21, 25).
On the Posterity of Cain and his Exile
[66] The son of Enoch is named Gaidad (Gen. 4:18), which means “a flock.” Such a name follows naturally upon his father’s name. For it was fitting that the man who deems himself beholden to mind, which is incapable of comprehending its own nature, should beget irrational faculties, collected into a flock; for men endowed with reason do not profess that creed.
On the Posterity of Cain and his Exile
[69] This is why Gaidad is said to have a son Maiel (Gen. 4:18), whose name translated is “away from the life of God.” For since the flock is without reason, and God is the Fountain of reason, it follows that he that lives an irrational life has been cut off from the life of God. Now Moses defines living in accordance with God as consisting in loving Him, for he says “thy life is to love Him that IS” (Deut. 30:19 f.).
