UKJV(i)
19 We have also a more sure word (o. logos) of prophecy; unto which all of you do well that all of you take heed, as unto a light that shines in a dark place, until the day dawn, and the day star arise in your hearts:
20 Knowing this first, that no prophecy of the scripture is of any private interpretation.
21 For the prophecy came not in old time by the will of man: but holy men of God spoke as they were moved by the Holy Spirit. (o. pneuma)
