2Pe 2 Peter, chapter Second Epistle of Peter, chapter 1
You can be sure that these matters are true, because we apostles ourselves witnessed that our Lord Jesus Christ is supremely great, and also because what the prophets say about him is completely reliable.
2 Peter 1:16-21
because no human beings decided to make those prophecies. On the contrary, those who spoke messages from God did that because it was the Holy Spirit who caused them to do it, and therefore the Spirit must help us to interpret/understand their meaning.1Pe 1:10
