Have you ever heard of people who try to make sure that others behave in a good way? Well, a committee for the propagation of virtue and the prevention of vice in the Gaza Strip is kind of like that.
The people in charge of this committee believe that it's important to encourage others to do good things and to prevent them from doing bad things. They want to make sure that everyone is following the laws and rules that they believe are important.
For example, they might encourage people to be kind to others or to help the less fortunate. They might also try to prevent people from doing things like stealing or hurting others.
This committee works to make sure that everyone in their community is living up to their standards of good behavior.
