2 Peter 1:19-21

Because of that experience, we have even greater confidence in the message proclaimed by the prophets. You must pay close attention to what they wrote, for their words are like a lamp shining in a dark place—until the Day dawns, and Christ the Morning Star shines in your hearts. Above all, you must realize that no prophecy in Scripture ever came from the prophet’s own understanding, or from human initiative. No, those prophets were moved by the Holy Spirit, and they spoke from God.
