Pesachim5: 10
קְרָעוֹ וְהוֹצִיא אֵמוּרָיו, נְתָנוֹ בְמָגִיס וְהִקְטִירָן עַל גַּבֵּי הַמִּזְבֵּחַ.  יָצְתָה כַּת רִאשׁוֹנָה וְיָשְׁבָה לָהּ בְּהַר הַבַּיִת, שְׁנִיָּה — בַּחֵיל, וְהַשְּׁלִישִׁית — בִּמְקוֹמָהּ עוֹמֶדֶת. חָשֵׁכָה — יָצְאוּ וְצָלוּ אֶת פִּסְחֵיהֶן.
He tore it [open] and removed its sacrificial parts, put them in a plate and burned them upon the altar.  The first group went out and remained on the Temple Mount, the second [group] in the Chel, and the third [group] remained where they were. After dark, they went out and roasted their pesach-offerings.
