Why does the Torah say 'oil' twice for the thanksgiving offering, when once would have been enough?
The episode is a lecture on Talmudic tractate Menachos, page 89. Rabbi Yaakov Nagel begins by examining the thanksgiving offering, questioning why the Torah mentions oil twice. This leads to a discussion of Rabbi Akiva's method of deriving the half-log oil measurement from this repetition. Rabbi Elazar ben Azaria strongly disagrees, arguing the measurement is from oral tradition, not scripture, and cites other laws like the eleven days between menstrual periods as similarly tradition-based. The lecture then addresses whether the log of oil is a fixed measure for all flour offerings, even massive sixty-isaron ones, with opinions from Rabbi Nechemiah and Rabbi Eliezer. A practical question about dryness is raised and briefly answered with the possibility of added water. The source for knowing a hin equals twelve logs is given via gematria from the word 'zeh'. The method for determining the half-log of oil for the menorah is described as a Temple trial-and-error process, starting with too much and reducing until it lasted the night, with a debate about whether to start high or low to avoid waste or stinginess. The permissibility of mixing wine libations for different offerings is discussed, hinging on whether the flour and oil have already been burnt. The episode details the flour and oil ratios for bull, ram, and lamb offerings, noting the lamb's oilier ratio of three logs per isaron. This difference explains restrictions on mixing their libations. Finally, the lecture covers a lamb brought with the omer offering and the requirements for a guilt offering slaughtered with improper intent, contrasting it with burnt offerings which have more flexibility.
