Greek to English Art/Literary Music Song Lyric

Hi,

This appears in an old song:

δόστου κόψιμο ο πασάς

I see from the Web that it is still used, but it is not in my Greek dictionary.

Does it by any chance imply a kind of cynicism? We are, after all, talking about an extremely authoritarian and corrupt regime here.

What is its etymology, please? I believe that δός is the ancient version of δώσε (give!), but I'm really not sure of anything here. However, if I'm right about δός, then presumably δόστου = Give him!

Nevertheless, I don't think I have the whole picture by any means. For one thing, the rest of the grammar doesn't fit a simplistic interpretation.

All the best,

Simon

PS This is from a Greek translation of Chekhov:
Κάθε λίγο και λιγάκι, κάθε μισή ώρα δόστου και μας έπαιρνε ο ταγματάρχης στο τηλέφωνο και μας ζητούσε κυλίνδρους και άλλους κι άλλους κυλίνδρους.
