Commentary for Meilah 2:4
הָעוֹלָה, מוֹעֲלִין בָּהּ מִשֶּׁהֻקְדְּשָׁה. נִשְׁחֲטָה, הֻכְשְׁרָה לְהִפָּסֵל בִּטְבוּל יוֹם וּבִמְחֻסַּר כִּפּוּרִים וּבְלִינָה. נִזְרַק דָּמָהּ, חַיָּבִין עָלֶיהָ מִשּׁוּם פִּגּוּל, נוֹתָר וְטָמֵא. וְאֵין מוֹעֲלִין בְּעוֹרָהּ, אֲבָל מוֹעֲלִין בַּבָּשָׂר עַד שֶׁיֵּצֵא לְבֵית הַדָּשֶׁן:
The [animal] <i>olah</i>, the laws of <i>meilah</i> apply once they have been sanctified. Once they were slaughtered they becomes susceptible to becoming ineligible [if touched] by a <i>tevul yom</i>, a <i>mechusar kippurim</i> and through <i>linah</i>. Once its blood has been sprinkled one is liable for <i>pigul</i>, <i>notar</i> and<i>tamei</i>. Its hides are not subject to meilah, but the meat is still subject to <i>meilah</i> until it goes out to the place of ashes.
Bartenura on Mishnah Meilah
English Explanation of Mishnah Meilah
When it is slaughtered it becomes susceptible to be disqualified through contact with a tevul yom or one who still requires atonement, or by remaining overnight.
Once its blood has been sprinkled it is subject to [the laws of] piggul, notar and defilement;
And the law of sacrilege does not apply to its hide, but it does apply to it flesh until [the ashes have been] removed [from the altar] to the place of the ashes.
Today’s mishnah deals with the animal olah.
Sections one-three: See mishnah two.
Section four: Immediately after it is slaughtered, the hide belongs to the priest. Therefore, the law of sacrilege stops applying to the hide. However, the law of sacrilege continues to apply to its flesh, which is not eaten by the priest. It only stops when the flesh is removed from the altar and brought to the place of ashes.
