<p>1:20 <i>Knowing this first, that no prophecy of scripture is of private interpretation</i>- To appreciate the force of Peter's argument in the previous verses, it must be understood most importantly (&quot;first&quot;) that prophetic Divinely inspired scripture is just that- it is not the personal interpretation of men, unlike the Jewish fables referenced in :16. &quot;Private interpretation&quot; is parallel with a word coming &quot;by the will of man&quot; (:21). We would better read the phrase as meaning that no prophetic, inspired word &quot;is private interpretation&quot;, the kind of personal interpretation or take on things which the Jewish fables were.</p>
