Avodah Zarah

It has been stated: The School of Rab said in the name of Rab: [The number of processes is] two and three;  but Samuel maintained that it is three and four.  Thus they taught in Sura, but in Pumbeditha they taught: The School of Rab said in the name of Rab: [The number of processes is] three and four; but Samuel maintained that it is four and five. Nor is there any contradiction [in the two versions], since the latter counts the final rinsing with water [as a separate process] whereas the former does not. The question was put to R. Abbahu: How is it with wicker-nets  used by Gentiles? — R. Abbahu answered: You have learnt the law: If his winepress and oil-press were defiled and he wished to prepare [wine or oil] in them in a state of purity, the boards [on the sides], the troughs and supporting-beams  must be rinsed, and as for the wicker-work, if it is made of willows and hemp, it must be scoured, but if of bast and reeds, it must remain unused for twelve months.  R. Simeon b. Gamaliel says: He leaves them from one period of wine-pressing to another and from one period of oil-pressing to another. But that agrees with the statement of the first Tanna!  — The issue between them is the matter of the early and late ripening [of the grapes].  R. Jose says: If he desires to purify them at once, he should pour over them boiling water or scald them with olive-water.  R. Simeon b. Gamaliel says in the name of R. Jose: He leaves them beneath a pipe through which there is a continuous stream of water or in a fountain with flowing water. For how long? — An 'onah.  The same provisions made with regard to yen nesek are made with regard to purification.  But is not the order reversed, since we are dealing here  with purification? — Rather [say] they made the same provisions with regard to yen nesek as they made for purification. How long is an 'onah? — R. Hiyya b. Abba said in the name of R. Johanan: Either a day or a night. R. Hana-She'ina — according to another version, R. Hana b. She'inah — reported that Rabbah b. Bar Hanah said in the name of R. Johanan: Half a day and half a night. R. Samuel b. Isaac said: There is no contradiction [in the two definitions], the former referring to the time of the spring and autumn equinox  and the latter to the summer and winter solstice. Rab Judah said: Filter-bags used by Gentiles, if made of hair, are to be rinsed, if of wool they must be scoured, and if of flax they must be left unused [for twelve months]; and if there be any knots in them they must be untied.  Wicker-baskets and strainers used by Gentiles, if plaited from strips of palm-fibre, must be rinsed,
