In the US today, when someone needs to pay for a ride to get somewhere, someone in the house may wait by the window to see when it arrives. And then they’ll call out “Time to go, the taxi’s here!”
In pre-war Eastern Europe, they would have called out “Der balagalah iz du — The wagon driver is here.”
And in that, lies all the difference.
זו היא כל התורה כולה ואידך פירושה הוא זיל גמור
This is the entire Torah, and the rest is explanation. Go learn!
– Hillel (to prospective convert), Shabbos 31a
