<p>4:5 <em>They are of the world. Therefore speak they of the world and the world hears them</em>- The world of the first century didn't generally hear the Jewish false teachers; but the Jewish world did. This confirms that we are correct in viewing &quot;the world&quot; here as the Jewish world. The message of these people, their teaching&nbsp;/ 'speaking', was of the Jewish world, and therefore attractive to the Jewish world.</p>
