They rushed to Jason's house in search of Paul and Silas in order to bring them out to the crowd. But when they did not find them, they dragged Jason and some other brothers before the city officials, shouting: 'These men who have caused trouble all over the world have now come here, and Jason has welcomed them into his house. They are all defying Caesar's decrees, saying that there is another king, one called Jesus.'
Since they could not find Paul and Silas, the mob grabbed Jason and other Christians and took them before the city officials. Then, they accused them of treason in hopes of eliminating the spread of the Truth. This is a pattern that occurs throughout history even to this day in that, if the facts do not support their opposition to the Gospel, Christians are accused of crimes such as treason and then they are persecuted.
