2 Peter 1:12-18

Therefore, I will always be ready to remind you of these things, even though you already know them and are established in the truth which is held firmly in your grasp. I think it right, as long as I am in this earthly tent, to inspire you by reminding you, knowing that the laying aside of this earthly tent of mine is imminent, as our Lord Jesus Christ has made clear to me. Moreover, I will diligently endeavor [to see to it] that even after my departure you will be able, at all times, to call these things to mind. For we did not follow cleverly devised stories or myths when we made known to you the power and coming of our Lord Jesus Christ, but we were eyewitnesses of His majesty [His grandeur, His authority, His sovereignty]. For when He was invested with honor and [the radiance of the Shekinah] glory from God the Father, such a voice as this came to Him from the [splendid] Majestic Glory [in the bright cloud that overshadowed Him, saying], “This is My Son, My Beloved Son in whom I am well-pleased and delighted”— [Matt 17:5] and we [actually] heard this voice made from heaven when we were together with Him on the holy mountain. [Matt 17:6]
