Talmud for Shevuot 2:2
אֶחָד הַנִּכְנָס לָעֲזָרָה וְאֶחָד הַנִּכְנָס לְתוֹסֶפֶת הָעֲזָרָה, שֶׁאֵין מוֹסִיפִין עַל הָעִיר וְעַל הָעֲזָרוֹת אֶלָּא בְמֶלֶךְ וְנָבִיא וְאוּרִים וְתֻמִּים וּבְסַנְהֶדְרִין שֶׁל שִׁבְעִים וְאֶחָד וּבִשְׁתֵּי תוֹדוֹת וּבְשִׁיר. וּבֵית דִּין מְהַלְּכִין וּשְׁתֵּי תוֹדוֹת אַחֲרֵיהֶם, וְכָל יִשְׂרָאֵל אַחֲרֵיהֶם. הַפְּנִימִית נֶאֱכֶלֶת וְהַחִיצוֹנָה נִשְׂרָפֶת. וְכֹל שֶׁלֹּא נַעֲשָׂה בְכָל אֵלּוּ, הַנִּכְנָס לְשָׁם אֵין חַיָּבִין עָלֶיהָ:
(He is liable for the offering) whether he enters the azarah [the first Temple court] or its [later]addition; for no addition is made to the city and to the azaroth without authorization [(for which reason it is sanctified as the first)] of the king, the prophet, the urim vetumim, the sanhedrin of seventy-one, the two thank-offerings, and song. The beth-din go, and the two thank-offerings behind them, and all of Israel behind them. The inner is eaten, and the outer burned. And if all of these do not obtain, if one enters there (in a state of uncleanliness), he is not liable (for an oleh veyored offering). [("with a king":) it being written (Exodus 25:9): "According to all that I show you: the form of the tabernacle, and the form of all its vessels, and thus shall you do." This ("and thus shall you do") is a superfluous verse, to be expounded as relating to future generations. And in the days of Moses, he was the king and the prophet, and his brother, the high-priest. And there were also the urim vetumim and the seventy elders — and thus for future generations. ("two thank-offerings":) two breads of thanksgiving. They would carry them in a circle until the end of the sanctified bound, where the first would be eaten, and the second burned. This is derived from (the rite of) Nechemiah ben Chachalyah, viz. (Nechemiah 12:31): "Then I presented two great thanksgivings." ("song":) they would chant (Psalms 30) "I shall extol You, O L rd, for You have uplifted me." And in the second Temple, even though there was neither king nor urim vetumim, the original sanctification of the Temple by Solomon "took" for its time and for the future, and what Nechemiah did was by way of commemoration alone.] And all (additions) that were made without all these (ceremonies) — If one (who were tamei) entered there, they (beth-din or the anointed high-priest as the case may be) are not liable (for a bullock of forgetfulness.)
