וַהֲבֵאתֶ֣ם שָׁ֗מָּה עֹלֹֽתֵיכֶם֙ וְזִבְחֵיכֶ֔ם וְאֵת֙ מַעְשְׂרֹ֣תֵיכֶ֔ם וְאֵ֖ת תְּרוּמַ֣ת יֶדְכֶ֑ם וְנִדְרֵיכֶם֙ וְנִדְבֹ֣תֵיכֶ֔ם וּבְכֹרֹ֥ת בְּקַרְכֶ֖ם וְצֹאנְכֶֽם׃
and thither ye shall bring your burnt-offerings, and your sacrifices, and your tithes, and the offering of your hand, and your vows, and your freewill-offerings, and the firstlings of your herd and of your flock;
Mishnah Terumot
From where do we derive that first-fruits must precede terumah, seeing that this one is called “terumah” and “the first” and the other is [also] called “terumah” and “the first”? Rather first-fruits take precedence since they are the first fruits of all produce. And terumah comes before the first tithe also because it is called “first.” And first tithe [precedes second tithe,] because it includes that which is called “first.”
