Bitter vetch of maaser sheni is eaten as shoots, and it may enter Jerusalem and leave. [If] it became tamei, R' Tarfon says: It is distributed into doughs; but the Sages say: It is redeemed. And [bitter vetch] of terumah, Beis Shammai say: We soak and pound it in taharah, but feed it in tumah. But Beis Hillel say: We soak it in taharah, but we pound and feed it in tumah. Shammai says: It is eaten dry. R' Akiva says: Everything done with it is [done] in tumah.
