חגי's question to the כהנים, and which liquids of the מקדש are 'pure' (רב vs. לוי)

Overview

This עמוד finishes an attempted proof from the question חגי הנביא asked the כהנים. The proof claims that wine and oil in the מקדש can become טמא. The גמרא rejects it, because it only works for רב, who already holds that altar liquids can become טמא. Next comes the full מחלוקת. רב says the כהנים erred, because the oil was a רביעי בקודש. שמואל says they were right, because the garment counts as an extra level, which makes the oil a חמישי. Each side is then challenged from the next פסוקים in חגי and defended. The גמרא then returns to יוסי בן יועזר's testimony. רב's version covers only the slaughterhouse liquids, while לוי's version covers all the altar liquids. The גמרא shows that לוי must agree with שמואל that the liquids can still become impure themselves, and that שמואל must accept רב's 'slaughterhouse' version. Finally, a ברייתא is quoted in support of each version, and the one for לוי is defended against a statement of רבי יהושע בן לוי.

Opening lines

וְאָמַר רַב: אִישְׁתַּבֻּשׁ כָּהֲנֵי.

And Rav said: The priests erred.

מִידֵּי הוּא טַעְמָא אֶלָּא לְרַב?

Is this reasoning valid for anyone other than Rav?

רַב ״מַשְׁקֵי בֵּית מַטְבְּחַיָּא״ תָּנֵי,

Rav teaches the testimony as 'the liquids of the slaughterhouse' [are pure],

אֲבָל מַשְׁקֵי בֵּי מַדְבְּחַיָּא — מְטַמֵּא.

but the liquids of the altar-house do become impure.

The steps (28)

  1. Proofרב says the priests made a mistake
  2. RejectionThe proof only works for רב, who already agrees
  3. StatementThe disagreement itself: did the priests err?
  4. Statementרב's reason: the oil was fourth-level impurity in sacred food
  5. Statementשמואל's reason: the oil was fifth-level, so pure is correct
  6. ChallengeWhere does שמואל get five levels from?
  7. ResolutionThe garment itself is the first level
  8. ChallengeChallenge to רב from the case of a person who is טמא מת
  9. ResolutionThe כהנים knew טומאת מת well but not טומאת שרץ
  10. Resolutionרבינא's different answer: the dead-body case was only a third level
  11. ChallengeThe verse calls their offerings impure, which is a problem for שמואל
  12. ResolutionThe verse is a surprised question, not a statement
  13. ChallengeBut 'all the work of their hands' sounds like a statement
  14. ResolutionTheir other sins are counted as if they offered in impurity
  15. StatementBack to יוסי בן יועזר: slaughterhouse liquids or altar liquids
  16. Statementלוי's view works if he agrees with שמואל
  17. ChallengeIf לוי agrees with רב, the case cannot be found
  18. Conclusionלוי must agree with שמואל
  19. Statementשמואל's view works if he agrees with רב's version
  20. ChallengeIf שמואל agrees with לוי's version, the fourth-degree detail makes no sense
  21. Conclusionשמואל must agree with רב's version
  22. StatementEach version has a supporting ברייתא
  23. ProofThe ברייתא that supports לוי
  24. Challengeרבי יהושע בן לוי says 'only in their place'
  25. Resolution'In their place' excludes a different case
  26. ChallengeBut he said 'in their place'
  27. Resolution'In their place' means where they became impure
  28. ProofThe ברייתא that supports רב
