민수기 25:21의 미슈나

A beast which was born on a festival all agree that it is permitted; and a chicken which was hatched from the egg all agree that it is forbidden. He who slaughters a wild animal or a bird on a festival Beth Shammai says: he may dig with a pronged tool and cover up [the blood] , but Beth Hillel says: he may not slaughter unless he has had earth made ready. But they agree that if he did slaughter he should dig with a pronged tool and cover up [the blood, and] that the ashes of a stove count as being prepared for the holiday.
