What do these lines mean?? I expect a line by line explanation please
Caesar tells Cimber not to crouch and plead in front of him for repealing his brother's exile declaration. He tells him that pleading and begging might flatter ordinary men, but he himself is unaffected by them. Caesar had already passed the decree of banishing Cimber's brother for his ill-deeds. He would not reverse his judgement. If Cimber continued to pray for mercy, then Caesar would have only disdain for him like that for an unkempt dog. He further says that he had done no wrong, as was his usual practice and he would not be satisfied with any plea without reasonable cause.
