These are the knots for which we are liable: the camel drivers’ knot and the sailors’ knot. And just as one is liable for tying them, so, too, is one liable for untying them. R’ Meir says: Any knot which one can untie with one hand, we are not liable for.

There are knots for which we are not liable as [we are for] the camel drivers’ knot and the sailor’ knot. A woman may tie the opening of her chemise; strings of a hair net or of a girdle; straps of a shoe or a sandal; [leather] canteens of wine or oil; or a pot of meat. R’ Eliezer ben Yaakov says: We may tie [a rope] in front of an animal in order that it not go out.  We may tie a pail with a belt but not with a rope. [But] R’ Yehudah permits [it]. R’ Yehudah stated a general rule: Any knot which is not permanent, we are not liable for.

We may fold garments even four or five times. We may make the beds on the night of the Sabbath for the Sabbath, but not on the Sabbath for the night after the Sab-bath. R’ Yishmael says: We may fold garments and make beds on Yom Kippur for the Sabbath; and fats of the Sabbath [sacrifices] may be offered on Yom Kippur. R’ Akiva says: Neither those of the Sabbath may be offered on Yom Kippur, nor may those of Yom Kippur be offered on the Sabbath.
