3,441. Ten Rows With Ten Barrels of Wine in Each

Hilchos Maaser 8:6

Let’s say that tevel got mixed with maaser from which terumas maaser wasn’t taken. If the volume of tevel was equal to that of the maaser, he must give up from the tevel a volume equal to the terumas maaser in it. For example, if 100 seah of tevel got mixed with 100 seah of maaser, he takes 101 seah from the mixture, which are considered maaser; the remaining 99 seah are considered tevel. If there was more tevel than tithes, he takes the tithes alone without giving up any of the tevel. This is because if he designated terumas maaser from the tevel, the tithes would be meduma – a mixture of secular produce and the terumas maaser of the tithes which were taken together. If there were more tithes than tevel, he designates the terumas maaser in the tevel, putting aside the tevel plus a volume equal to the terumas maaser of the tevel, which is 1/100 of the tithe. The tevel should be treated as entirely meduma and sold to a kohein minus the cost of the two parts terumah in it. We therefore find that he loses 1/100 of the tithes, which is equal to the volume of terumas maaser in the tevel. Therefore, if there were 100 seah of tevel with 200 seah of tithes, he puts aside 103 seah: three seah of terumas maaser from the 100 seah of tevel and the terumas maaser for the 200 seah of tithes. This is done to keep people from erring if tithes get mixed with the same volume of tevel. Therefore, one leaves 197 seah to be tithes as before.

Let’s say that someone has ten rows with ten barrels of wine in each. He designates one barrel from the outer row as tithes for the rest but he doesn’t know from which outer row. In such a case, he takes two barrels from the diagonals, mixes their contents and takes the tithes from the resulting mixture.
