YEDI'AH THAT ENABLES BITUL (Yerushalmi Orlah Perek 2 Halachah 1 Daf 11a)

.

(a)

Question: Obviously, his Yedi'ah (knowledge that one Isur fell in before the second fell in) permits (it is not as if both Isurim fell at once). Does his friend's Yedi'ah permit?

.

1.

What is the case? He did not know, and his friend knew.

.

(b)

Question: Does Safek Yedi'ah (perhaps one Isur fell in) permit?

Answer #1: There were two boxes in front of him. One has 200 [Sa'im], and one does not have 200. A Se'ah of Orlah fell into one of them, and it is not known into which it fell. Afterwards a second [Se'ah of Orlah] fell into one of them, and he measured it and found in it 202. (Now we know that also the first fell into it.)

If you will say that Safek Yedi'ah is like Vadai Yedi'ah, [the first became Batel, and now also the second] is Batel (in 201). If you will say that Safek Yedi'ah is not like Vadai Yedi'ah, (it is as if two Sa'im fell into 200), and they are not Batel.

Answer #2: There was one box. It is a Safek whether it has 200 [Sa'im], or it does not. A Se'ah of Orlah fell, and it is not known whether it fell into it or did not fall [into it]. Afterwards a second [Se'ah of Orlah] fell into it, and he measured it and found in it 202. (Now we know that also the first fell into it.)

If you will say that Safek Yedi'ah is like Vadai Yedi'ah, it is Batel (like above). If you will say that Safek Yedi'ah is not like Vadai Yedi'ah, it is not Batel.
