¹⁶ All Scripture is God-breathed^(A) and is useful for teaching,^(B) rebuking, correcting and training in righteousness,^{(C) 17} so that the servant of God^[a](D) may be thoroughly equipped for every good work.^(E)

¹⁹ We also have the prophetic message as something completely reliable,^(A) and you will do well to pay attention to it, as to a light^(B) shining in a dark place, until the day dawns^(C) and the morning star^(D) rises in your hearts.^{(E) 20} Above all, you must understand^(F) that no prophecy of Scripture came about by the prophet’s own interpretation of things. ²¹ For prophecy never had its origin in the human will, but prophets, though human, spoke from God^(G) as they were carried along by the Holy Spirit.^(H)

¹⁸ I warn everyone who hears the words of the prophecy of this scroll:^(A) If anyone adds anything to them,^(B) God will add to that person the plagues described in this scroll.^{(C) 19} And if anyone takes words away^(D) from this scroll of prophecy,^(E) God will take away from that person any share in the tree of life^(F) and in the Holy City, which are described in this scroll.
