Finishing the 11th chapter and beginning the 12th chapter. First, how much wool must one give in terms of worth? And how must it be presented? And how do we know how much wool counts as this gift to the kohen? The source is in the verses in the same context as the “first fleece” mitzvah in the Torah, in Deuteronomy. Note the famous proverb about reaching for too much as an unsuccessful project, whereas a less ambitious grasp will be successful. Plus, the discussion of the kohen’s sash — namely, if there was no wool in the kohen’s sash, then why the first fleece? The Gemara steps back to say that wool is used for the kohen gadol’s clothing, and the sash applies to everyone, basically, and therefore the measure of how much fleece is required. Also, chapter 12! And a new mishnah — all about the mitzvah of sending away the mother bird to take the eggs/baby birds, which, together with honoring parents, carry a biblical promise of long life.
