2 Peter 1:19-21
King James Version
19 We 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:

20 Knowing this first, that no prophecy of the scripture is of any private interpretation.

21 For 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.
