Sifra
2) Or go in this direction. It is written here "terumah," and, in respect to bikkurim (first-fruits) "terumah" (Devarim 12:17). Just as "terumah" of bikkurim has no limit, this, too, has no limit!
Sifrei Devarim
"and the offering of your hands": These are bikkurim, as it is written (Ibid. 26:4) "and the Cohein shall take the basket from your hands and he shall place it before the altar of the L-rd your G-d."
Sifrei Devarim
(Devarim 12:17) "You shall not be able to eat in your gates": R. Yehoshua b. Karchah says (in respect to "able"): I am able, but not permitted. A cognate instance is (Joshua 15:63) "But the Yevussi, the inhabitants of Jerusalem, they could not drive out": They could but they were not permitted to do so.
