Academic Thinking Lesson 10

First, a big thank you for the lessons in scholarly thinking. Fascinating, joyful, and clear things, as if you were given at Sinai itself. Blessed are you and blessed is your mother who was blessed to be enlightened by the Torah in this way.
You mentioned at the beginning of the lesson, another lesson by a rabbi (whose name I was unable to catch on the recording) on ​​three laws in the language of consecration. Which rabbi is this, and can you refer to the aforementioned lesson (assuming there is documentation of it)?
All the best, Sela.
