משנה על בכורים 1:1

Regarding terumah and bikkurim:One is liable to death And the [additional] fifth; And they are forbidden to non-priests; And they are the property of the priest; And they are neutralized in a hundred and one parts; And they require the washing of hands; And the setting of the sun. These [laws] apply only to terumah and bikkurim, but not to tithe.

Ben Antigonus brought up firstlings from Babylon, but they did not accept from him. Joseph the priest brought first fruits of wine and oil, but they did not accept from him. He also brought up his sons and members of his household to celebrate Pesah katan in Jerusalem, but they turned him back, so that the thing should not become firmly fixed as an obligation. Ariston brought his first fruits from Apamea and they accepted from him, because they said, one who buys [a field] in Syria is as one who buys [a field] in the outskirts of Jerusalem.
