Talmud for Shabbat 225:5

HALAKHAH: Mishnah. “A donkey may go out with its saddle cloth,” etc. Samuel said, if it was tied to it from before the Sabbath. Ḥanin from Gophtia said before Samuel, Rav Ḥiyya bar Ashi does not act like this. He told him, Rav uses kleisterin, as it was stated: rams go out with kleisterin³⁷It is not clear what this means. One possibility is κλεῖστρον, τό = κλεῖθρον “bar, boom, fence”. Rosh who quotes the paragraph in extenso (Chapter 5 No. 2) reads טרסקל which is a feeding basket bound to the animal’s head. Such a feeding basket is appropriate for cattle used for agricultural work; it is inappropriate for rams. Also since rams are not dangerous, except maybe for competing rams, there seems to be no reason why rams should be muzzled. The only explanation for a lock for rams would be a contraption which would prevent the ram to mount ewes except under control of the owner. This is accepted in Mishnah 2.. Rebbi Aḥa bar Papa objected before Rebbi Zeˋira: But was it not stated³⁸Babli 113a.: a rope tied to a cow may be tied to the feeding trough, the feeding trough may be tied to a cow. One understands a cow’s may be tied to the feeding trough. May from the feeding trough be tied to a cow? Would he not use the animal’s sides on the Sabbath³⁹Since it is biblically forbidden to ride animals on the Sabbath it is rabbinically forbidden to lean on animals. In harnessing an animal it is difficult to avoid leaning on it.? Rebbi Abba said, explain it for knots which are not permanent⁴⁰This is difficult to understand. Since making a permanent knot is a biblical violation of the Sabbath (Mishnah 7:2) it is clear that all tying of ropes on the Sabbath must be loops that are easily undone.. Rebbi Yose said, is there a difference for sides of an animal whether the knot is permanent or not permanent? Rebbi Shammai said, explain it following Rebbi Simeon ben Eleazar, as it was stated, Rebbi Simeon ben Eleazar said, it is permitted to use the sides of an animal on the Sabbath⁴¹As anonymous opinion Babli 154b.. There is no difference between sides of an animal and sides of a tree⁴²Since biblically it is forbidden to cut a branch from a tree, rabbinically it is forbidden to climb it on the Sabbath.. Rebbi Mana said, I confirmed it if he connects rope to rope⁴³If the cow is lead to or from the feeding trough, it is not touched at all but a rope attached to the trough is tied or untied to the rope around the cow’s neck..
