“The priest shall offer one as a sin offering, and one as a burnt offering, and atone for him, for what he sinned regarding the corpse, and he shall sanctify his head on that day” (Numbers 6:11). “The priest shall offer one as a sin offering, and one as a burnt offering," that the priest will designate them, one as a sin offering and one as a burnt offering in the course of their preparation. I have only designation by the priest, from where do I derive by the owner?
It is stated regarding a birth mother: “She shall take two turtledoves or two young pigeons, one as a burnt offering and one as a sin offering" (Leviticus 12:8); the owners designate [them] at the time they buy them. Consequently, we have learned here: Designation by the priest and designation by the owner. And consequently, we have learned here: An undesignated pair, when is the priest required to designate them?
When the owners set them aside for an offering but left them undesignated. And consequently, we have learned here: A designated pair is when the owners designated which is for a burnt offering, and which is for a sin offering. “And atone for him, for what he sinned regarding the corpse,” due to impurity from corpses, this is the statement of Rabbi Yishmael. Rabbi Elazar says: Since he sinned against his soul, as he afflicted himself by abstaining from wine.
Are these matters not inferred a fortiori? If one who afflicted himself by abstaining from wine requires atonement, all the more so one who afflicted himself by abstaining from all matters.124This is the basis for the opinion of the Sage that anyone who fasts is called a sinner (Ta’anit 11a). “He shall dedicate to the Lord the days of his naziriteship, and he shall bring a lamb in its first year as a guilt offering and the first days shall be void, as his naziriteship was impure” (Numbers 6:12).
“And shall sanctify his head on that day…He shall dedicate to the Lord the days of his naziriteship” (Numbers 6:11–12); consequently, we have learned that someone begins counting from the day that he shaved, this is the statement of Rabbi Yosei ben Rabbi Yehuda. Rabbi says: “And atone for him, for what he sinned regarding the corpse, and shall sanctify his head on that day” (Numbers 6:11) – on the day of the bringing of his offerings.
