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.
