2 Peter 1:20 YLT

¹⁸  and this voice we -- we did hear, out of heaven borne, being with him in the holy mount.

¹⁹  And we have more firm the prophetic word, to which we do well giving heed, as to a lamp shining in a dark place, till day may dawn, and a morning star may arise -- in your hearts;

²⁰  this first knowing, that no prophecy of the Writing doth come of private exposition,

²¹  for not by will of man did ever prophecy come, but by the Holy Spirit borne on holy men of God spake.
