- Herr Doktor is a traditional German title, roughly equivalent to the more-known "Doctor of Medicine (MD)" or "Juris Doctor (JD)".
- Is the allusion to Moses due to this story being post-war/unification and Moses is a Jewish figure? (There might be technicalities between "Jew", "Israelite", and "Abrahamic" but I'm even more ignorant here than I am of German customs.)
- Is "space on the stone tablets", "11th Commandment" an allusion to the (in)famous German noun-phrases? Like "Wohnungsgeberbestatigung" which is actually three words (trans: "apartment-provider's confirmation"/"landlord's confirmation").
So...explainer from anyone who got this line?
