In "Der Golem" of Gustav Meyrink, Schemajah Hillel says:
Einen Augenblick versank er in Nachdenken, und ich hörte ihn einen hebräischen Satz murmeln: »Lischuosècho Kiwisi Adoschem.«
In the Ukrainian translation there's an explanation: I hope for your help, God!
But I can't find those words anywhere to check if it really means what is said in Ukrainian translation.
It says in the novel that it's a Hebrew sentence. It might also be Yiddish, as it is a saying of the rabbi said in the Prague Jewish ghetto. Where should I look for this expression?
