2 Peter 1:16-18 NIV

[16] For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty. [17] He received honor and glory from God the Father when the voice came to him from the Majestic Glory, saying, “This is my Son, whom I love; with him I am well pleased.” [18] We ourselves heard this voice that came from heaven when we were with him on the sacred mountain.
