2. Petrus 2:5

eighth--that is, Noah, and seven others. Contrasted with the densely peopled "world of the ungodly." preacher--not only "righteous" himself (compare Pe2 2:8), but also "a preacher of righteousness": adduced by Peter against the licentiousness of the false teachers (Pe2 2:2) who have no prospect before them but destruction, even as it overtook the ungodly world in Noah's days.

The apostle, having in the foregoing chapter exhorted them to proceed and advance in the Christian race, now comes to remove, as much as in him lay, what he could not but apprehend would hinder their complying with his exhortation. He therefore gives them fair warning of false teachers, by whom they might be in danger of being seduced. To prevent this, I. 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 tells us how contrary the method is which God takes with those who fear him (Pe2 2:7-9). IV. He fills up the rest of the chapter with a further description of those seducers of whom he would have them beware.

2:5 The second example of judgment is that God did not spare the ancient world at the time of Noah. In the flood, God destroyed all human life apart from Noah and his family (see Gen 6–8).
