Topic

The amounts of oil in the משנה: half a לוג for the תודה, one לוג per מנחה or per עשרון, the נסכים measured in הין and לוג, and half a לוג per lamp of the מנורה.

Overview

The amud opens by finishing an earlier point: even the mouths of the מנורה's lamps must be made of pure gold. The גמרא then works through the oil amounts listed in the משנה. For the תודה, רבי עקיבא learns half a לוג from the double ״בַּשֶּׁמֶן״, read as a ריבוי אחר ריבוי that comes to limit. Half of that oil goes to the רביכה. רבי אלעזר בן עזריה says the half לוג is instead a הלכה למשה מסיני. Next, the חכמים hold that each עשרון of flour needs one לוג of oil, while רבי נחמיה and רבי אליעזר בן יעקב say every מנחה gets only one לוג. Each side explains how it uses the other side's words in the poor מצורע's פסוק. The גמרא then gives the sources for the נסכים amounts, using the fact that a הין is twelve לוגין, and for the half לוג per lamp of the מנורה, which the חכמים measured to last all night. The amud ends with the start of a new משנה about which נסכים may be mixed together.
