How to edit or hide "Your comments are subjected to administrator's moderation"?

After the last update I find the message "Your comments are subjected to administrator's moderation" at the bottom of each article.

1. This message is displayed in English although my site is in German.
2. Since it is written in red it looks like an error message. So I like to not show it at all.

How can I hide or at least edit/translate this message?

Thanks for your help!
