Pesachim 83 - 30 Shvat, Rosh Chodesh Adar, February 12

Study Guide Pesachim 83

Parts of the sacrifice that are leftover (notar), and bones and sinews must be burned, as since they cannot be eaten, they become leftover. But they are not to be burned on the fifteenth of Nissan as it is a Yom Tov, or on the sixteenth if it falls on a Shabbat. Rabbi Yitzchak said: Notar by rabbinic decree passes on impurity to hands that touch it, therefore also bones that have marrow from the Pesach sacrifice and cannot be eaten and thereby become leftover, since breaking the bones is forbidden, also pass on impurity to hands. The gemara tries to bring support for this and also raise a question against him. According to Rav, the sinews are considered meat, other than the sinews in the neck. The gemara raises a difficulty from our mishnah and brings some resolutions. Why is one not permitted to burn the leftovers on Shabbat / Yom Tov?
