who killed both the Lord Jesus and their own prophets, and drove us out, and didn't please God, and are contrary to all men;
Because there was a lot of contention raised by the unbelieving Jews there in Thessalonica against Paul. We are told in the book of Acts that they were contentious because they were envious at the great crowds. By the time the third Sabbath came, the whole town had gathered together to listen to the message that Paul was proclaiming, and the Jews became envious, jealous.And so they then stirred up a group of men who were of the base sort to beat them, to lie against them, to false . . . to give false charges. These men are against Rome. They're rebelling against Rome and all, and perpetrated, of course, the beatings of them and the imprisonment in the dungeon. So as they preached the gospel in Thessalonica, these Jews stirred up contention there and they were so contentious that when they heard that they'd heard that they've gone to Berea, they came down to Berea to stir up trouble down in Berea.
