If an animal died, one may not move it from its place. There was an incident and they asked R’ Tarfon about this matter and about challah which had contracted tumah-contamination. He entered the house of study and asked. They said to him, ‘‘He may not move them from their place.’’

We may not be counted initially for [the meat of] an animal on Yom Tov, but we may be counted for it[s meat] prior to Yom Tov, and slaughter and apportion [it] among ourselves. R’ Yehudah says: A person may weigh meat against a utensil or against a chopper. But the Sages say: We may not use a scale at all.
