2 Peter 1:16-21

16For we have not followed cunningly devised fables, when we made known to you the power and coming of our Lord Jesus Christ, but were eyewitnesses of his majesty. 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
