399. Verse 17 And Cain knew his wife, and she conceived and bore Enoch. And he was building a city, and he called the name of the city after the name of his son Enoch.
'Cain knew his wife, and she conceived and bore Enoch' means that this schism or heresy produced another from itself which was called 'Enoch'. 'A city that was built' means every detail of doctrine and heresy arising out of it. It is because that schism or heresy was called Enoch that the statement is made about the name of the city being called after the name of his son Enoch.
