3,354. Black Figs and White Figs
Terumos 13:16
Let’s say that there were two piles of grain and their owner declared that the terumah for both of them is in one of them. In such a case, both piles are meduma. If there were two seah of grain and one grain pile, and the owner declared that one of those seah is terumah for the pile, then one of them is terumah but we don’t know which. If there were two piles of grain and one seah, and he declared the seah terumah for one of the piles, then the seah is terumah for one of the piles, but we don’t know which pile is not tevel (untithed produce).
Terumos 14:1
Let’s say that there were 50 black figs and 50 white figs and one fig of terumah fell among them. If it was white, all the black figs remain permitted but the white figs are meduma. If it was black, the black figs are meduma and the white figs remain permitted. If we don’t know whether it was white or black, it is nullified in a mixture 101 times the volume of the terumah fig. If he originally knew what kind of fig it was but he subsequently forgot, all the figs are meduma.
