Reference for Tamid 1:3
נָטַל אֶת הַמַּפְתֵּחַ וּפָתַח אֶת הַפִּשְׁפָּשׁ, וְנִכְנַס מִבֵּית הַמּוֹקֵד לָעֲזָרָה, וְנִכְנְסוּ אַחֲרָיו וּשְׁתֵּי אֲבוּקוֹת שֶׁל אוּר בְּיָדָם. וְנֶחְלְקוּ לִשְׁתֵּי כִתּוֹת, אֵלּוּ הוֹלְכִים בָּאַכְסַדְרָא דֶּרֶךְ הַמִּזְרָח, וְאֵלּוּ הוֹלְכִים בָּאַכְסַדְרָא דֶּרֶךְ הַמַּעֲרָב. הָיוּ בוֹדְקִין וְהוֹלְכִין עַד שֶׁמַּגִּיעִין לִמְקוֹם בֵּית עוֹשֵׂי חֲבִתִּים. הִגִּיעוּ אֵלּוּ וָאֵלּוּ, אָמְרוּ שָׁלוֹם, הַכֹּל שָׁלוֹם. הֶעֱמִידוּ עוֹשֵׂי חֲבִתִּים לַעֲשׂוֹת חֲבִתִּים:
He [the supervising priest] took the key and opened the small door [located in the Chamber of Fire] and entered from the Chamber of Fire to the Courtyard. And they [the other priests] entered after him with two torches of fire were in their hands. They would split into two groups. [One group] walked under the portico [surrounding the Courtyard] towards the east and [the other group] walked under the portico towards the west. They would check [the temple vessels] and walk until they reached the place where the <i>Chavitim</i> [loaves of bread brought as meal offering]. They [the two groups] met each other and would say, "It is fine, all is fine," [the vessels are in order]. They would appoint [from their group] makers of the <i>Chavitim</i> to make the <i>Chavitim</i>.
