“And as they were speaking to the people, the priests and the captain of the temple and the Sadducees came upon them, greatly annoyed because they were teaching the people and proclaiming in Jesus the resurrection from the dead. And they arrested them and put them in custody until the next day, for it was already evening. But many of those who had heard the word believed, and the number of the men came to about five thousand.”
Acts 4:1-4 ESV

I find a few details interesting & encouraging in this text:
1) the reason for the arrest - they were preaching Jesus. The proclamation of Jesus as the good news to mankind is annoying to those who delight in their own fancies or pursue high places of ruler ship & authority.
2) the fruit of gospel preaching - many believe the Word thus, by implication, were birthed into the family of God. Followers of Jesus who experience persecution due to preaching need be reminded of the fruit that such bears.
