Hello! "To urge" means to strongly advise or try to persuade someone to do a particular thing. "urge something on/upon somebody" has the same meaning " to strongly advise" as in " I have urged upon him the need for extreme secrecy."

Hi Mah. According to the definitions below you can see that they are very similar in meaning. To urge = to advise someone very strongly about what action or attitude they should take To insist = to say very firmly that something must happen or must be done To answer your question ; yes they both mean the same thing, they are synonyms.
