Sotah7: 7
בִּרְכוֹת כֹּהֵן גָּדוֹל כֵּיצַד? חַזַּן הַכְּנֶסֶת נוֹטֵל סֵפֶר תּוֹרָה וְנוֹתְנָהּ לְרֹאשׁ הַכְּנֶסֶת, וְרֹאשׁ הַכְּנֶסֶת נוֹתְנָהּ לַסְּגָן, וְהַסְּגָן נוֹתְנָהּ לְכֹהֵן גָּדוֹל, וְכֹהֵן גָּדוֹל עוֹמֵד וּמְקַבֵּל וְקוֹרֵא עוֹמֵד, וְקוֹרֵא ”אַחֲרֵי מוֹת”, וְ”אַךְ בֶּעָשׂוֹר”. וְגוֹלֵל אֶת הַתּוֹרָה וּמַנִּיחָהּ בְּחֵיקוֹ, וְאוֹמֵר: ”יוֹתֵר מִמַּה שֶּׁקָּרִיתִי לִפְנֵיכֶם כָּתוּב כָּאן”. ”וּבֶעָשׂוֹר” שֶׁבְּחוּמַשׁ הַפְּקוּדִים קוֹרֵא עַל פֶּה, וּמְבָרֵךְ עָלֶיהָ שְׁמוֹנֶה בְרָכוֹת: עַל הַתּוֹרָה, וְעַל הָעֲבוֹדָה, וְעַל הַהוֹדָיָה, וְעַל מְחִילַת הֶעָוֹן, וְעַל הַמִּקְדָּשׁ, וְעַל יִשְׂרָאֵל, וְעַל הַכֹּהֲנִים, וְעַל שְׁאָר הַתְּפִלָּה.
In what manner were the blessings of the Kohen Gadol [recited]? The attendant of the synagogue takes a Torah scroll and gives it to the head of the synagogue, the head of the synagogue gives it to the Deputy [Kohen Gadol], and the Deputy gives it to the Kohen Gadol. The Kohen Gadol stands up and accepts [the scroll] and reads while standing.  He reads [from the passage that begins,] After the death (Leviticus 16:1) and [the passage that begins,] But on the tenth (Leviticus 23:26-32). Then he rolls up the Torah [scroll], puts it in his bosom, and says, “There is more than I have read to you written here;” and he recites by heart from the Book of Numbers, beginning, On the tenth (Numbers 29:7-11).  Then he recites over it eight benedictions: for the Torah; for the [sacrificial] service; for the thanksgiving; for the forgiveness of sin; for the Temple; for Is-rael; for the Kohanim; and for the rest of the prayer.
