3,374. Four Things Are Called Terumah
Terumos 15:19
A pot used to cook terumah may not be used to cook secular produce. If it was cooked in such a pot, the food is prohibited if the taste of the terumah is discernible. If one washes the pot with wine or water after cooking the terumah, then one may cook secular food in it. If terumah was cooked in only part of the pot, then one need not wash out the whole pot, just the part where it was cooked.
Terumos 15:20
Terumah gedolah, terumas maaser, challah and bikkurim (first fruits) are all called “terumah.” Regarding terumas maaser, the Torah says, “You shall remove the terumah of God from it" (Numbers 18:26) and that it is treated “like the terumah of your grain pile” (ibid. 15:20). Regarding challah, the same verse says, “You shall take challah as terumah.” Deut. 12:17 says, “Do not eat in your gates the tithes of your grain, your wine and your oil ... and the terumah of your hand.” The only thing in this verse not named explicitly that must be eaten in Jerusalem is bikkurim, so we see that the term “terumah of your hand” must mean first fruits, which are also called terumah.
