II Peter 1:19-21

King James Version

19We have also a more sure word of prophecy; whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn, and the day star arise in your hearts: 20Knowing this first, that no prophecy of the scripture is of any private interpretation. 21For the prophecy came not in old time by the will of man: but holy men of God spake as they were moved by the Holy Ghost.

New King James Version

19And so we have the prophetic word confirmed, which you do well to heed as a light that shines in a dark place, until the day dawns and the morning star rises in your hearts; 20knowing this first, that no prophecy of Scripture is of any private interpretation, 21for prophecy never came by the will of man, but holy men of God spoke as they were moved by the Holy Spirit.

New International Version

19And we have the word of the prophets made more certain, and you will do well to pay attention to it, as to a light shining in a dark place, until the day dawns and the morning star rises in your hearts. 20Above all, you must understand that no prophecy of Scripture came about by the prophet's own interpretation. 21For prophecy never had its origin in the will of man, but men spoke from God as they were carried along by the Holy Spirit.
