He describes these seducers as impious in themselves, and very pernicious to others (Pe2 2:1-3). II. He assures them of the punishment that shall be inflicted on them (Pe2 2:3-6). III.

He fills up the rest of the chapter with a further description of those seducers of whom he would have them beware.
