2 Peter 2:5

And spared not the old The antediluvian; world, but saved Noah Interposed amidst the general ruin for the preservation of one good man and his family; the eighth person, a preacher, &c. Bishop Pearson translates this clause, the eighth preacher of righteousness; supposing that Enoch, (Genesis 5:24,) from whom Noah was descended, was the first preacher of righteousness, and that all the intermediate persons were likewise preachers thereof, and that Christ preached by them all. But of this there is no evidence; and it seems certain that Enoch could not be the first preacher of righteousness: Adam was, in a wonderful manner, fitted to perform that office in the first world, as Noah was in the second; and what excellent instructions both might give, is easy to be conceived! Bishop Pearson adds, that if the above-mentioned sense of the passage be not admitted, it may be understood as denoting, not the order in which Noah was ranked, but merely the number of persons that were with him, namely, Noah with seven others, or Noah one of eight. By terming Noah a preacher, κηρυκα, a crier, or herald, of righteousness, Peter intimates that all the time Noah was preparing the ark, he proclaimed to the antediluvians the destruction of the world by a flood, that from the dread of that impending judgment of God they might be brought to repentance. His preaching, however, it appears, was attended with little or no success. Bringing in the flood In a gradual, but irresistible manner; upon the world of the ungodly Whose numbers stood them in no stead.
