Text Excerpt
הניתנין במתנה אחת שנתערבו בניתנין במתנה אחת – ינתנו במתנה אחת. (מהן) מתן ארבע במתן ארבע – ינתנו במתן ארבע.
In a case of the blood of an offering that is to be placed on the altar with one placement that was mixed with the blood of another offering that is to be placed on the altar with one placement, e.g., the blood of a firstborn offering with the blood of another firstborn offering or the blood of an animal tithe offering, the blood should be placed with one placement. In a case of the blood of an offering that is to be placed on the altar with 4 placements that was mixed with the blood of another offering that is to be placed on the altar with 4 placements, e.g., the blood of a sin offering with that of another sin offering, or the blood of a burnt offering with that of a peace offering, the blood should be placed with 4 placements.
מתן ארבע במתנה אחת – רבי אליעזר אומר: ינתנו במתן ארבע, רבי יהושע אומר: ינתנו במתנה אחת.
If the blood of an offering that is to be placed on the altar with 4 placements was mixed with the blood of an offering that is to be placed on the altar with one placement, R' Eliezer says: The blood should be placed with 4 placements. R' Yehoshua says: The blood should be placed with one placement, as the priest fulfills the requirement with one placement after the fact.
אמר לו רבי אליעזר: הרי הוא עובר על בל תגרע! אמר ליה רבי יהושע: הרי הוא עובר על בל תוסיף!
R' Eliezer said to R' Yehoshua: According to your opinion, the priest violates the prohibition of: Do not diminish, as it is written: “All these matters that I command you, that you should observe to do; you should not add thereto, nor diminish from it” (Deuteronomy 13:1). One may not diminish the number of required placements from 4 to one. R' Yehoshua said to R' Eliezer: According to your opinion, the priest violates the prohibition of: Do not add, derived from the same verse. One may not add to the one required placement and place 4.
