Shabbat

because they are boiled seven times, and if one does not remove it [the edible portion], it goes rancid, hence it is like [picking] the non-edible out of the edible. GRINDING. R. Papa said: He who cuts up beets very fine is liable on account of grinding. R. Manasseh said: He who cuts chips [for fuel] is liable on account of grinding. Said R. Ashi: If he is particular about their size, he is liable on account of cutting. KNEADING AND BAKING. R. Papa said: Our Tanna omits the boiling of ingredients [for dyes],  which took place in [connection with] the Tabernacle, and treats of baking!  — Our Tanna takes the order of [making] bread. R. Aha son of R. Awira said: He who throws a tent peg into a stove  is liable on account of cooking. But that is obvious? — You might say, His intention is to strengthen [harden] the article,  therefore we are informed that it [first] softens and then hardens. Rabbah son of R. Huna said: He who boils pitch is liable on account of cooking. But that is obvious? — You might argue, Since it hardens again, I might say [that he is] not [liable]. Hence he informs us [otherwise]. Raba said: He who makes an [earthenware] barrel is culpable on account of seven sin-offerings.  [He who makes] an oven is liable on account of eight sin-offerings.  Abaye said: He who makes a wicker work is liable to eleven sin-offerings,  and if he sews round the mouth thereof, he is liable to thirteen sin-offerings. SHEARING WOOL AND BLEACHING. Rabbah b. Bar Hanah said in R. Johanan's name: He who spins wool from off the animal's back on the Sabbath incurs three sin-offerings, one on account of shearing, another on account of hackling, and the third on account of spinning.  R. Kahana said: Neither shearing, hackling, nor spinning is [done] in this manner.  But is it not so? Surely it was taught in the name of R. Nehemiah: It was washed [direct] on the goats and spun on the goats:  which proves that spinning direct from the animal is designated spinning? — Superior skill is different. Our Rabbis taught: He who plucks the wing [of a bird], trims it [the feather], and plucks it [the down], is liable to three sin offerings. Said R. Simeon b. Lakish: For plucking [the wing] one is liable on account of shearing; for trimming [the feather] he is liable on the score of cutting; and for plucking [the down] he is liable under the head of smoothing. TYING AND UNTYING. Where was there tying in the Tabernacle?  — Said Raba: The tent-pegs were tied. But that was tying with the intention of [subsequent] untying?  But said Abaye: The weavers of the curtains, when a thread broke, tied it up. Said Raba to him: You have explained tying; but what can be said about untying? And should you answer that when two knots [in the material] chanced to come together, one untied one and left the other knotted:  [it may be asked], seeing that one would not do thus before a king of flesh and blood, how much more so before the Supreme King of kings, the Holy One, blessed be He?  Rather said Raba — others state, R. Elai: Those who caught the hillazon  tied and untied. SEWING TWO STITCHES. But it cannot endure?  — Said Rabbah b. Bar Hanah in R. Johanan's name: Providing that he knots them. TEARING IN ORDER TO SEW TWO STITCHES. Was there any tearing in the Tabernacle? — Rabbah and R. Zera both say:
