What do the men do when they seize Daniel?

Hello! Thank you for your question. 
The section that you are asking about is in Chapter 4, where Simon takes Daniel to the synagogue in order to try to seek a glimpse of Jesus of Nazareth. Near the end of the chapter, Daniel attempts to throw a rock at two Roman soldiers when he is grabbed by two men. 
The two men are minor characters and stop Daniel from his attempt at riling up the Romans. Their ultimate goal is to stop him (very possibly saving his life) and to scold him for his joining in with zealots to cause trouble. Seeing as how the Jews at the time were completely under Roman rule, it is understandable that these men would have wanted to prevent any action that would have caused the Romans to impose more harsh control over them.
