"I seem to remember telling you both that I would have to expel you if you broke any more school rules," said Dumbledore.
Ron opened his mouth in horror.
"Which goes to show you that the best of us must sometimes eat our words," Dumbledore went on, smiling. "You will both receive Special Awards for Services to the School and…two hundred points apiece for Gryffindor."

I don't exactly understand "the best of us" here. What does it mean?
Best Answer
Even those of us who rarely make mistakes [the best of us] must sometimes admit we have made one.
The best of us refers to the members of a group who excel in some way that is pertinent to the group's identity, focus, or sense of purpose and duty. The group can be a small one or it can include everybody.
