Catalan to English Art/Literary Poetry & Literature Song Text

Hi

First of all, heartfelt best wishes to you and your country at this critical juncture of events.

I think this line is from an older version of the National Anthem. The way I remember it being sung 40 years ago was with an alternating line in each chorus, something like this:
Chorus 1
Bon cop de falç!
Bon cop de falç, quan vulguin moure brega!
Bon cop de falç!
Chorus 2
Bon cop de falç!
Bon cop de falç, ?????!
Bon cop de falç!
Chorus 3
Bon cop de falç!
Bon cop de falç, defensors de la terra!
Bon cop de falç!

Please give a literal translation (as well) so I can see how the grammar works.

Best wishes, and many thanks,

Simon
