2Pet 1:16-18

Eyewitnesses of Christ's Glory 16For we did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we had been eyewitnesses of his majesty.17For he received honor and glory from God the Father when that voice was conveyed to him by the Majestic Glory, saying, “This is my Son, my Beloved, with whom I am well pleased.”18We ourselves heard this voice come from heaven, while we were with him on the holy mountain.
