I don't believe that they 'combined' the meanings, as whoever knows enough of both languages to be hired as a professional translator, almost certainly knows at least as much as I've said here, and probably much more. If there is a single point I want readers to come away with, it's that Oshite Mairu (and humble language in general) is very difficult to translate into other languages. "The end has come" is just artistic license, but it's not particularly out of place.

If it helps, Oshite implies compulsion, so you could see it as Hakumen's duty (as the continua 'equalizer') compelling him to fight Ragna (preventing the coming of the Black Beast).
