['On Shabbat, one may move even four or five baskets of straw and baskets of produce, due to the guests, who require that place to sit, and due to suspension of Torah study in the study hall, where space is required to seat the students. However, one may not move these items to create space in the storeroom. One may move ritually pure teruma, although it may only be eaten by a priest; and doubtfully tithed produce [demai], which may not be eaten until tithes are separated from it due to concern that an am ha’aretz did not separate its tithes; and first tithe whose teruma of the tithe has already been taken and given to priests; and second tithe and consecrated items that were redeemed; and even dry lupine, which is not fit for consumption by a person, because it is goat food. However, one may neither move untithed produce, nor first tithe whose teruma has not been taken, nor second tithe and consecrated items that were not redeemed, nor raw arum and raw mustard, as all of these items are not fit for consumption and are therefore set aside. Rabban Shimon ben Gamliel permits moving in the case of arum because it is food for ravens.', 'With regard to bundles of straw, and bundles of wood, and bundles of twigs, if one prepared them on Shabbat eve for animal food, one may move them. And if not, one may not move them. One may overturn a basket in front of the chicks so that they can climb on and climb off of it. Likewise, with regard to a hen that fled that one seeks to retrieve, one may push it even with his hands until it reenters the house. One may help calves and foals to walk, and likewise a woman may help her son to walk. Rabbi Yehuda said: When is it permitted? When her son picks one foot up and puts one foot down by himself. However, if her son were dragging both his feet, it would be prohibited because it would be like carrying him in the public domain.', 'One may not birth an animal on a Festival, and all the more one may not birth it on Shabbat. However, one may assist it to give birth. And one may birth a woman even on Shabbat, and call a midwife for her to travel from place to place, even when the midwife’s travel involves the desecration of Shabbat. And one may desecrate Shabbat for a woman giving birth. And one may tie the umbilical cord of a child born on Shabbat. Rabbi Yosei says: One may even cut the umbilical cord. And all the requirements of circumcision may be performed for a baby whose eighth day of life occurs on Shabbat.']
