2 Peter 1:17-21 New King James Version (NKJV)

¹⁷ For He received from God the Father honor and glory when such a voice came to Him from the Excellent Glory: “This is My beloved Son, in whom I am well pleased.” ¹⁸ And we heard this voice which came from heaven when we were with Him on the holy mountain.

¹⁹ And so we have the prophetic word confirmed,^[a] 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; ²⁰ knowing this first, that no prophecy of Scripture is of any private interpretation,^{[b] 21} for prophecy never came by the will of man, but holy men of God^[c] spoke as they were moved by the Holy Spirit.
