And with what may it not go out? A camel may not go out with a patch on its tail, nor with its forelegs and hind legs chained together, nor with its foreleg bent back to the shoulder; and so [it is] with all other animals. One may not tie camels to one an-other and lead them, but he may gather ropes into his hand and lead them, provided he does not wind [the ropes one around the other].
