399. Verse 17. And Cain knew his wife, and she conceived, and bare Enoch; and he was building a city, and called the name of the city after the name of his son, Enoch. The words "Cain knew his wife, and she conceived and bare Enoch" signify that this schism or heresy produced another from itself that was called "Enoch." By "the city which he built" is signified all that was doctrinal and heretical therefrom, and because the schism or heresy was called "Enoch" it is said that "the name of the city was called after the name of his son, Enoch."
