These lines are spoken by Casca about Julius Caesar. Casca is describing how Caesar is so beloved by the people that even things that might seem offensive or inappropriate from someone else would be seen as virtuous or praiseworthy when done by Caesar.

This suggests Caesar's ability to manipulate and control public opinion, a key factor in his rise to power.
