2-е Петра 1:20

"Forasmuch as ye know this" (Pe1 1:18). first--the foremost consideration in studying the word of prophecy. Laying it down as a first principle never to be lost sight of. is--Greek, not the simple verb, to be, but to begin to be, "proves to be," "becometh." No prophecy is found to be the result of "private (the mere individual writer's uninspired) interpretation" (solution), and so origination. The Greek noun epilusis, does not mean in itself origination; but that which the sacred writer could not always fully interpret, though being the speaker or writer (as Pe1 1:10-12 implies), was plainly not of his own, but of God's disclosure, origination, and inspiration, as Peter proceeds to add, "But holy men . . . spake (and afterwards wrote) . . . moved by the Holy Ghost": a reason why ye should "give" all "heed" to it. The parallelism to Pe2 1:16 shows that "private interpretation," contrasted with "moved by the Holy Ghost," here answers to "fables devised by (human) wisdom," contrasted with "we were eye-witnesses of His majesty," as attested by the "voice from God." The words of the prophetical (and so of all) Scripture writers were not mere words of the individuals, and therefore to be interpreted by them, but of "the Holy Ghost" by whom they were "moved." "Private" is explained, Pe2 1:21, "by the will of man" (namely, the individual writer). In a secondary sense the text teaches also, as the word is the Holy Spirit's, it cannot be interpreted by its readers (any more than by its writers) by their mere private human powers, but by the teaching of the Holy Ghost (Joh 16:14). "He who is the author of Scripture is its supreme interpreter" [GERHARD]. ALFORD translates, "springs not out of human interpretation," that is, is not a prognostication made by a man knowing what he me…

In this chapter we have, I. An introduction, or preface, making way for, and leading to, what is principally designed by the apostle (Pe2 1:1-4). II. An exhortation to advance and improve in all Christian graces (Pe2 1:5-7). III. To enforce this exhortation, and engage them seriously and heartily to comply with it, he adds, 1. A representation of the very great advantage which will thereby accrue to them (Pe2 1:8-11). 2. A promise of the best assistance the apostle was able to give to facilitate and forward this good work (Pe2 1:12-15). 3. A declaration of the certain truth and divine origin of the gospel of Christ, in the grace whereof they were exhorted to increase and persevere.

1:20-21 came from the prophet’s own understanding (or is a matter of one’s own interpretation): The point is probably that the prophets were not left on their own to interpret the visions that God gave them. God made the meaning clear to the prophets, so that they could prophesy clearly and reliably.
