2 Peter 1:16-18

16 When we told you about the power and coming of our Lord Jesus Christ, we did not follow any clever myths. Rather, we were eyewitnesses of his majesty.

17 For he received honor and glory from God the Father when the voice of the Majestic Glory was conveyed to him as follows: "This is my Son, whom I love. I am pleased with him."

18 We ourselves heard this voice that came from heaven when we were with him on the holy mountain.
