2 Peter 1:12

“Wherefore I will not be negligent, etc.] The apostle having made use of proper arguments to excite the saints he writes to regard the exhortation he had given, to the diligent exercise of grace, and discharge of duty, proceeds to give the reasons of his own conduct, why he gave such an exhortation to them, and pressed it, and continued to do so, and determined for the future to go on with it, as particularly the usefulness and profitableness of it; and therefore, seeing it would be attended with so many advantages before mentioned, he was resolved that he would not be careless, nor omit any opportunity that should offer: to put you always in remembrance of these things; of the exercise of…”

“1:12-15 Peter was writing at the end of his life, and 2 Peter is similar to works that belong to a popular Jewish genre called the testament, in which an old and respected leader gives final instructions to his children or others on his deathbed (cp. Deut 31–33; Josh 24). This genre is especially well known from a Jewish work called The Testaments of the Twelve Patriarchs.”
