A [person who is] tahor [in regard] to [mei] chatas who touched an oven: [If he touched it] with his hand, [he is] tamei. And [if he touched it] with his foot, [he is] tahor.  [If] he was standing on top of an oven and stretched his hand outside [the airspace of] the oven with the flask in it, and [similarly if] a pole is placed on top of the oven and on it are two jugs, one on this side and one on that side, R’ Akiva declares [the contents of the flask and jug] tahor and the Sages declare [the contents of the flask and jug] tamei.

[If] he was standing outside [the airspace of] an oven and he stretched his hands to a window, took the flask, and passed it over the top of the oven, R’ Akiva declares [it] tamei and the Sages declare [it] tahor. But this [person who is] tahor for chatas may stand on top of the oven with an empty utensil that is tahor for chatas in his hand, or [with a utensil filled] with water that is not sanctified.

[If] a flask of [mei] chatas touched [a flask] of sacrificial food or of terumah, the [flask] of [mei] chatas is [rendered] tamei, [whereas] the [flask] of sacrificial food or of terumah is [declared] tahor. [If] both [flasks] are in his two hands, both of them are [rendered] tamei.  [If] both [flasks] are [wrapped] in separate papers, both of them are tahor.  [If] the [flask] of [mei] chatas is [wrapped] in paper and the [flask] of te-rumah is [placed directly] in his hand, both are [rendered] tamei.  [If] the [flask] of terumah is [wrapped] in paper and the [flask] of [mei] chatas is [directly] in his hand, both of them are tahor. R’ Yehoshua says: [The flask] of [mei] chatas is [rendered] tamei.  [If] they were placed on the ground and he touched them, [the flask] of mei chatas is tamei, [whereas the flask] of sacrificial food or of terumah is tahor.  [If] he caused them to move, R’ Yehoshua [declares it] tamei and the Sages [declare it] tahor.

A flask [containing mei chatas] that someone left uncovered, and upon returning he finds it covered, is unfit [for chatas use]. [If] he left it covered and upon returning he found it uncovered, if a weasel can drink from it, or a snake [according] to [the] words of R’ Gamliel, or dew descends into [the flask] at night, [the mei chatas] is unfit [for chatas use].  Chatas is not saved [from tumah by a] sealed cover. [However,] water that is not sanctified is saved [from tumah by means of a] sealed cover.
