One who throws an unclean object from one place to another: [for instance] a loaf among keys or a key among loaves, [that which was clean remains] clean. Rabbi Judah says: if a loaf was thrown among keys the former becomes unclean, but if a key was thrown among loaves the latter remain clean.

A dead sheretz that was held in the mouth of a weasel that was passing over loaves of terumah and it is doubtful whether the sheretz did or did not touch them, in such condition of doubt [the loaves] are clean.

A weasel that had in its mouth a [dead] sheretz or a dog that had carrion in its mouth and they passed between clean [persons] or if clean persons passed between them, their condition of doubt is deemed clean, since the uncleanness , had no resting place. If they were picking at them while these lay on the ground, and a person stated, "I went to that place but I do not know whether I did or did not touch it," his condition of doubt is deemed unclean, since the uncleanness had a resting place.

An olive's bulk of corpse was held in a raven's mouth and it is doubtful whether it overshadowed a person or vessels in a private domain: The person's condition of doubt is deemed to be unclean But the vessels’ condition of doubt is deemed clean. One who drew water in ten buckets and a dead sheretz was found in one of them, it alone is deemed unclean but all the others remain clean. If one poured out from one vessel into another and a dead sheretz was found in the lower vessel, the upper one remains clean.

On account of six doubtful cases of uncleanness terumah is burned: On account of the doubt of a bet ha-peras [grave area], On account of earth about which there is doubt whether it came from the land of the gentiles, On account of a doubt about the garments of an ‘am ha-arez; On account of a doubt about found vessels found by chance; On account of found spit, On account of a doubt about human urine that was near the urine of a beast. On account of a certainty of having touched these which causes the doubtful uncleanness, terumah is burned. Rabbi Yose says: also on account of their doubtful contact in a private domain; But the sages say: in a private domain the terumah is only held in suspense and in a public domain it is deemed clean.

These are the cases of doubtful uncleanness that the sages declared to be clean:A doubt concerning drawn water for a mikveh, A doubt concerning an object of uncleanness that floated upon the water. A doubt concerning liquids as to whether they have contracted uncleanness it is deemed unclean, but if it was whether uncleanness has been conveyed it is deemed clean. A doubt concerning the hands as to whether they have contracted uncleanness, have conveyed uncleanness or have attained cleanness, they are deemed clean. A doubt that arose in a public domain; A doubt concerning an ordinance of the scribes; A doubt concerning non-sacred food; A doubt concerning a sheretz; A doubt concerning negaim; A doubt concerning a nazirite vow; A doubt concerning a first-born; A doubt concerning sacrifices.

"A doubt concerning an object of uncleanness that floated upon water:" [It is clean] whether the water was in vessels or in the ground. Rabbi Shimon says: if in vessels he is deemed unclean but if in the ground he is deemed clean. Rabbi Judah says: if the doubt arose when the man went down into the water he is deemed unclean, but if when he came up he is deemed clean. Rabbi Yose says: even if there is only enough room for a man and the uncleanness the former remains clean.

"In the case of a doubt concerning liquids as to whether they have contracted uncleanness it is deemed unclean:" How so? If an unclean person stretched his foot between clean liquids and there is doubt whether he touched them or not, such a condition of doubt is deemed to be unclean. If a man had an unclean loaf in his hand and he stretched it out between clean liquids, and there is doubt whether it touched them or not, such a condition of doubt is deemed to be unclean. "But if it was whether uncleanness has been conveyed, it is deemed clean." How so? If a man had in his hand a stick on the end of which there was an unclean liquid and he threw it among clean loaves and there is doubt whether it touched them or not, such a condition of doubt is deemed clean.

Rabbi Yose says: a condition of doubt in the case of liquids is deemed unclean in respect of food and clean in respect of vessels. How so? If there were two jars, the one unclean and the other clean, and he made dough with the contents of one of them and a doubt arose as to whether he prepared it with the contents of the unclean, or of the clean one, such is "a condition of doubt in the case of liquids [which] is deemed unclean in respect of food and clean in respect of vessels."

"If there is doubt concerning the hands as to whether they have contracted uncleanness, have conveyed uncleanness or have attained cleanness, they are deemed clean." "Any doubt that arose in a public domain is deemed clean. "A condition of doubt concerning an ordinance of the scribes": [For instance, he is uncertain whether] he ate unclean food or drank unclean liquids, whether he immersed his head and the greater part of his body in drawn water, or whether there fell on his head and the greater part of his body three log of drawn water, such a condition of doubt is deemed clean. But if a condition of doubt arose concerning a father of uncleanness even though it was only rabbinical, it is deemed unclean.

"A condition of doubt concerning non-sacred food"--this refers to the cleanness practiced by Pharisees. "A condition of doubt concerning a sheretz" –according [to their condition at] the time they are found. "A condition of doubt concerning negaim" it is deemed clean in the beginning before it had been determined to be unclean, but after it had been determined to be unclean, a condition of doubt is deemed unclean. "A condition of doubt concerning a nazirite vow" [in such a condition of doubt he] is permitted [all that is forbidden to a nazirite]. "A condition of doubt concerning first-borns" whether they are human firstborn or firstborn of cattle, whether the firstborn of an unclean beast or a clean one, for the one who wishes to extract from his fellow bears the burden of proof.

"And a condition of doubt concerning sacrifices" if a woman has experienced five doubtful cases of miscarriage or five discharges of doubtful zivah she brings only one sacrifice and may then eat other sacrifices, she being under no obligation to bring the remainder.
