Talmud do Kelim 19:13

“If it shrank it is in order.” Rebbi Immi said, that means for the seeds that were already on it; hence, it is forbidden to sow anew. If one transgressed and sowed, since the earlier ones are permitted, so are the new ones. Rebbi Jeremiah asked: It is acceptable that if the later ones were uprooted, the earlier ones are permitted. If the earlier ones were uprooted, what is the status of the later ones? Let us hear from the following⁵²Mishnah Kelim 19:6. One has to read ארוכות instead of ארובות. One speaks of a bed that has a wooden frame, consisting of two short (head- and foot-) boards and two long ones on the sides. The mattress lies on strings that are strung from one long board to the opposite one. The bed has become impure. It is a utensil, and any utensil can become pure either by immersion in a ritual bath (which is a problem for a large bed) or by becoming unusable. The Mishnah states that if the two long boards are broken we no longer have a bed and the remainder becomes pure, even if the boards are later replaced by new ones. But if the long boards are simply removed and replaced by new ones, the impurity is not removed, even if the replacement boards break, since the old ones could be returned to their place.: “If the two long boards of a bed were removed and one made two new ones in their stead but did not change the holes, if the new boards were broken, it is impure, if the old ones, it is pure, since all goes after the prior status.” That means, if the later ones were uprooted, the earlier ones are permitted. If the earlier ones were uprooted, the later ones are forbidden.

“One tightens.” ¹⁴⁶Babli 10a a different version of the entire argument Rebbi Yasa said, Ḥizqiah and Rebbi Joḥanan disagree. Ḥisqiah said: making a lattice, warp and woof; tightening, either warp or woof. Rebbi Joḥanan said: making a lattice, either warp or woof; tightening, if it is loose he tightens it. Rebbi Ḥiyya bar Abba said, everybody agrees that making a lattice means warp and woof. Where do they disagree? About tightening. Ḥisqiah said: either warp or woof; Rebbi Joḥanan said: if it is loose he tightens it. Rebbi Yasa instructed Samuel bar Ḥanina that “making a lattice” means warp and woof. We do not know whether this follows Ḥizqiah or it follows Rebbi Ḥiyya bar Abba and everybody’s opinion. Rebbi Abun bar Ḥiyya said before Rebbi Ze`ira: a Mishnah says so that making a lattice means warp and woof, as we have stated there¹⁴⁷Mishnah Kelim 19:1., “when is the rope connected to the bed¹⁴⁸That impurity is transferred from one to the other.? If he plaited three boxes.” Could you say warp without woof or woof without warp? Could one pitch woof and make a lattice?
