2 Pedro 3

15 And reckon the long-suffering of our Lord, to be for salvation; as also our beloved brother Paul, according to the wisdom given to him, has written to you.

16 As, indeed, in all his epistles, speaking in them concerning these things: in which there are some things hard to be understood, which the untaught and unstable wrest, as they do also the other scriptures, to their own destruction.
