Two mishnayot: Mishnah 1 – When the burnt offering is disqualified, the kohanim won’t get the hide of the offering, depending on when the disqualification took place, and why it’s been disqualified (for example, not brought in the name of the right offering – which would not fulfill the person’s obligation in bringing that offering, but the kohanim would get the hide). The Gemara focuses on what it means that the offering belongs to a person, but not hekdesh (and not that of a convert). Plus, the limud/learning that teaches that the kohanim get the hides of kodshei kodshim, and the hides of the kodshei kalim go to the owners who bring the offerings. Mishnah 2 – What happens to the hides when they’ve already been flayed from the offering, before disqualification? Rabbi Hanina, deputy high priest, said he never saw the hides going out to be burnt – which leads Rabbi Akiva to draw conclusions that the sages then rebut.
