Now those [believers] who had been scattered went from place to place preaching the word [the good news of salvation through Christ].

So, when Peter and John had given their testimony and preached the word of the Lord, they started back to Jerusalem, preaching the good news [about salvation] in many Samaritan villages [along the way].

Then Philip spoke and beginning with this Scripture he preached Jesus to him [explaining that He is the promised Messiah and the source of salvation].

and there they continued to preach the good news.

And when he had seen the vision, we (including Luke) tried to go on into Macedonia at once, concluding that God had called us to preach the gospel to them.
