19. And we have the prophetic word [made] firmer still. You will do well to pay close attention to it as to a lamp shining in a dismal (squalid and dark) place, until the day breaks through [the gloom] and the Morning Star rises (comes into being) in your hearts.
20. [Yet] first [you must] understand this, that no prophecy of Scripture is [a matter] of any personal or private or special interpretation (loosening, solving).
21. For no prophecy ever originated because some man willed it [to do so–it never came by human impulse], but men spoke from God who were borne along (moved and impelled) by the Holy Spirit.
