<p>4:13 <em>For I bear witness that he has worked hard for you and for those in Laodicea and for those in Hierapolis</em>- On :11 we noted that Paul considered these brethren, along with himself, to be 'working' for the Kingdom's cause whilst incarcerated. In :12 he observes how Epaphras was always striving in prayer &quot;for you&quot;. I suggest therefore that the hard work AV &quot;great zeal&quot; in view refers to the work of prayer. And he also prayed not only for Colosse but for those he knew in Laodicea and Hierapolis. </p>
