Zevachim5: 8
הַבְּכוֹר, וְהַמַּעֲשֵׂר, וְהַפֶּסַח, קָדָשִׁים קַלִּים — שְׁחִיטָתָן בְּכָל מָקוֹם בָּעֲזָרָה, וְדָמָן טָעוּן מַתָּנָה אַחַת, וּבִלְבַד שֶׁיִּתֵּן כְּנֶגֶד הַיְסוֹד. שִׁנָּה בַאֲכִילָתָן: הַבְּכוֹר נֶאֱכָל לַכֹּהֲנִים, וְהַמַּעֲשֵׂר לְכָל אָדָם; וְנֶאֱכָלִין בְּכָל הָעִיר, [לְכָל אָדָם,] בְּכָל מַאֲכָל, לִשְׁנֵי יָמִים וְלַיְלָה אֶחָד. הַפֶּסַח אֵינוֹ נֶאֱכָל אֶלָּא בַלַּיְלָה, וְאֵינוֹ נֶאֱכָל אֶלָּא עַד חֲצוֹת, וְאֵינוֹ נֶאֱכָל אֶלָּא לִמְנוּיָיו, וְאֵינוֹ נֶאֱכָל אֶלָּא צָלִי.
The bechor-offering, the maaser-offering, and the pesach-offering [are] offerings of lesser holiness — their slaughter may be anywhere in the Courtyard, and their blood requires one application, but he must apply it opposite the base. They differ in [the manner of] their consumption: The bechor-offering is eaten [only] by Kohanim, and the maaser-offering by anyone; and they may be eaten throughout the city, [by anyone,] prepared in any manner, for two days and one night. The pesach-offering may be eaten only by night, it may be eaten only until midnight, it may be eaten only by those registered for it, and it may be eaten only roasted.
