I realized tonight that I mistakenly numbered shiur 1246 as 1426 and that I have continued in that erroneous numbering since then both in the listing and at the beginning of each recording. I will fix them in the listing. I am sorry for the mix-up!
Meseches Kalla Rabbasi is one of the מסכתות קטנות usually printed at the end of the volume of מסכת עבודה זרה in the standard שסי"ן. We are using Rabbi Chaim Kanievsky זצ"ל's ביאור, which is similar in style to his ביאור on תלמוד ירושלמי, but we also include on screen the text from Sefaria.com. It is noteworthy that כלה רבתי is comprised not just of ברייתות, but also of גמרות.
