Machshirin 4:4 - 4:5

חבית שירד הדלף לתוכה (the jug into which water leaking from the roof came down) – that re not acceptable/intentional, and within it (i.e., the jug) are fruit and he doesn’t want that they become fit to receive ritual defilement.

ישבר – that if he empties it out, he transfers the water from here to there intentionally and it is found that the fruit are made fit to receive ritual defilement.

ומודים – The School of Shammai [agrees] with the School of Hillel.

שהוא מושיט את ידו וכו' הן טהורין (that he puts his hand in – and takes pieces of fruit out – and they are not fit for uncleanness) – meaning to say, that they were not made fit through this.

הניתזין (that are splashing) – from it outwards.

והצפין (that which overflows the vessel) – above and goes outward. All of them are not [considered as] under the law of “when water is put” (Leviticus 11:38), because they are not done intentionally, and similarly the water that is inside of them.

נטלה לשפכה – that he did not pour them out in their place but rather he took the trough to pour the water out in another place, they are [considered as] under the law of “when water is put,” for they are done intentionally, since he did not pour them out immediately there in their place.

ובית הלל אומרים – since he did not leave them there but took them to pour them, they are not [considered as] under the law of “when water is put.”

הניחה – if he left the trough there from the outset in order that the drippings from the roof would come down upon it.

אלו ואלו – The School of Shammai and the School of Hillel agree that even though that he took it and afterwards poured it out, they are under the law of “when water is put,” since he had already considered/intended it.

מים העולים בידיו – that he washes [his clothing] with them, and it is satisfactory to him.

ברגליו – it is not satisfactory to him.

אא"כ נטנפו רגליו (unless his feet become muddy/soiled) – they are under the law of “when water is put,” anything that he would fill in a jar that is mentioned above, for water that comes up after it is under the law of “when water is put,” as it is explained above, because it is impossible for water to enter into it until they touch its outside (but the Halakha does not follow Rabbi Eliezer).
