Bikkurim1: 9
וּמִנַּיִן שֶׁהוּא חַיָּב בְּאַחֲרָיוּתָן עַד שֶׁיָּבִיא לְהַר הַבַּיִת? שֶׁנֶּאֱמַר: ,,רֵאשִׁית בִּכּוּרֵי אַדְמָתְךָ תָּבִיא בֵּית ה' אֱלֹהֶיךָ”, מְלַמֵּד שֶׁחַיָּב בְּאַחֲרָיוּתָם עַד שֶׁיָּבִיא לְהַר הַבָּיִת.  הֲרֵי שֶׁהֵבִיא מִמִּין אֶחָד וְקָרָא, וְחָזַר וְהֵבִיא מִמִּין אַחֵר — אֵינוֹ קוֹרֵא.
And from where [do we learn] that he is responsible for them until he brings [them] to the Temple Mount? For it is stated (Exodus 23:19): The earliest of the bikkurim of your ground you shall bring to the House of Hashem your God. [This] teaches that he is responsible for them until he brings [them] to the Temple Mount.  [If] one brought [bikkurim] from one species and recited [the declaration] and he then brought [bikkurim] again from another species, he does not recite.
