And Moshe and the kohanim the Leviim spoke to all Israel, saying: Keep silence and hear, O Israel; this day you have become a people to Hashem your God.
English: “Haskes” — form groups (kittot) and occupy yourselves with Torah, for the Torah is acquired only in company. As R’ Yosei son of R’ Chanina said: “A sword is upon the boasters” — these are Torah scholars who study Torah alone (bad be-vad).
On the daf: The rare word הסכת is read as an acronym / play on עשו כתות. Torah study in isolation is criticized; acquisition requires a chavurah.
Type of Learning
Custom (derasha on a unique biblical word).
What Is Learned
