2 Peter 1:17-21

17For he received from God the Father honour and glory, when there came such a voice to him from the excellent glory, This is my beloved Son, in whom I am well pleased. 18And this voice which came from heaven we heard, when we were with him on the holy mount.

19We have also a more sure word of prophecy; to which ye do well that ye take heed, as to 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 prophecy came not in old time by the will of man: but holy men of God spoke as they were moved by the Holy Spirit.1
