A job I applied to three weeks ago, was reposted on Glassdoor 3 days ago with a changed job description, should I update and resubmit my application?

I applied to a generic job listing in my field three weeks ago, while looking for more jobs, I noticed it was updated to provide information about the specific position. My cover letter and resume are good for the generic posting, but could be updated to address the specific tasks of this role. Should I update my cover letter and resume and resubmit?
