<p>8:4 <em>Therefore those who were scattered-</em> Gk. 'the diaspora'. They were diaspora Jews who had come back from their dispersion to live in Jerusalem. But now they were again a diaspora, but of the Jerusalem church.</p><p><em>Went about preaching the word</em>- Acts 11:19 informs us that these brethren went as far as Phenice and Cyprus preaching the word. Most of the Jerusalem church were comprised of the 'devout men' from throughout the Roman world who had come to end their days at Jerusalem, and now had been baptized into Christ by Peter. It's logical to assume that Saul's persecution prompted them to return home- and thus the Gospel spread.</p>
