Mishnah Zavim 5:7: One who touches the discharge of a zav, his spittle, his semen, his urine, or the blood of a menstruant, he renders unclean at two [levels], and disqualifies [terumah] at one [level more]. If he separated himself [from the source of uncleanness], he renderds unclean at one [level] and renders unfit [terumah] at one [level more]. [The law is the same] whether one touched [it] or moved [it]. Rabbi Eliezer says, even if he carried [it].

הנוגע בזובו של זב, וברקו, בשכבת זרעו, במימי רגליו, ובדם הנדה, מטמא שנים ופוסל אחד. פרש, מטמא אחד ופוסל אחד, אחד הנוגע ואחד המסיט. רבי אליעזר אומר, אף הנושא:

Mishnah Zavim 5:8: If one [a clean person] carries something which was ridden upon [i.e. a saddle] or if he was carried on it, or if he moved it, he renders unclean at two [levels], and disqualifies [terumah] at one [level more]. If he separated himself [from the source of uncleanness], he renderds unclean at one [level] and renders unfit [terumah] at one [level more]. If one carried the corpse of an animal or the water [mixed with the ashes] of [the red heifer] sin offering of which there was sufficient for a sprinkling [because ashes of a red cow are mixed in] of an amount that can be sprinkled, he renders unclean at two [levels], and disqualifies [terumah] at one [level more]. If he separated himself [from the source of uncleanness], he renderds unclean at one [level] and renders unfit [terumah] at one [level more].

הנושא את המרכב והנשא עליו והמסיטו, מטמא שנים ופוסל אחד. פרש, מטמא אחד ופוסל אחד. הנושא את הנבלה, ואת מי חטאת שיש בהם כדי הזיה, מטמא שנים ופוסל אחד. פרש, מטמא אחד ופוסל אחד:
