Zevahim 84: The Ups and Downs (But Mainly Ups) of the Altar

On the debate over what items can be taken down from the altar, and which must remain here - and then, against the backdrop of the several tannaitic views, the decision was made. With libations in a different category from the offerings themselves, apparently. Also, a new mishnah! Paying new attention to that which became invalidated before bringing them into the courtyard, let alone on the altar... With a specific list, including idolatry, bestiality, and more. Also, the Gemara on this mishnah that addresses 3 exclusions from the altar - as brought in a beraita -- exclusions for which the blood indeed would be brought down. Specifically, assessing Rabbi Yehudah's view.
