Anybody know Greek?

A reader writes:

I would like to ask you for your help. I’m writing a new novel and I would need to know how you say “The Suffering Servant” (you know, as in the Isaiah passages) in Greek (preferably the ancient Septuagint Greek).

I can’t speak a word of these ancient languages, but that alone would greatly enrich my novel.

Could you summon your army of sycophants to help me on this? I would be most grateful if you could.
