[Regarding] partners who designated terumah one after the other, R' Akiva says: Both their “terumos” are terumah. But the Sages say: The terumah of the first is terumah. R' Yose says: If the first [partner] separated an [appropriate] amount of te-rumah, the terumah of the second [partner] is not terumah; but if the first [partner] did not separate an [appropriate] amount of terumah, the terumah of the second [partner] is terumah.
