Halocho #1009 - is today's fast (עשרה בטבת) mentioned in the Bible?

The prophet יְחֶזְקֵאל was told to record the 10th day of the 10th month (Tevet, counting from Nissan) as the day the the siege started:

 וַיְהִי דְבַר ה' אֵלַי בַּשָּׁנָה הַתְּשִׁיעִית, בַּחֹדֶשׁ הָעֲשִׂירִי, בֶּעָשׂוֹר לַחֹדֶשׁ, לֵאמֹר.   בֶּן-אָדָם, כְּתָב לְךָ אֶת-שֵׁם הַיּוֹם--אֶת-עֶצֶם, הַיּוֹם הַזֶּה: סָמַךְ מֶלֶךְ-בָּבֶל אֶל-יְרוּשָׁלִַם, בְּעֶצֶם הַיּוֹם הַזֶּה. 

 יְחֶזְקֵאל פרק כד:א-ב

The prophet זְכַרְיָה prophesied that the fast of the 4th month (Tammuz, counting from Nissan), the fast of the 5th month (Av) and the fast of the 10th month (Tevet) will be turned into days of joy.

 כֹּה-אָמַר ה'... צוֹם הָרְבִיעִי וְצוֹם הַחֲמִישִׁי וְצוֹם הַשְּׁבִיעִי וְצוֹם הָעֲשִׂירִי יִהְיֶה לְבֵית-יְהוּדָה לְשָׂשׂוֹן וּלְשִׂמְחָה, וּלְמֹעֲדִים, טוֹבִים; וְהָאֱמֶת וְהַשָּׁלוֹם, אֱהָבוּ. 

זְכַרְיָה פרק ח:יט

Today's Mincha consists of אַשְׁרֵי,  half-Kaddish and Torah reading. The 3rd Aliya also reads the Haftarah (דִּרְשׁוּ from יְשַׁעְיָהוּ) . Only somebody who is fasting should be called up to the Torah on a fast day.

After the 3 Brachot following the Haftara (until מָגֵן דָּוִד) , the Torah is returned to the Aaron HaKodesh followed by half-Kaddish and the Amida.

During the Mincha Amida, individuals add the "עֲנֵנוּ" prayer into the 16th Bracha; שְׁמַע קוֹלֵנוּ. If one forgot, one does not need to make amends.

The Chazzan adds עֲנֵנוּ during both Shacharit and Mincha, as a separate Bracha before רְפָאֵנוּ. 

Even at Mincha he adds Birkat Cohanim (or בָּרְכֵנוּ בַּבְּרָכָה הַמְשֻׁלֶּשֶׁת) after Modim.

The final Bracha is שִׂים שָׁלוֹם , since there was Torah reading.

The repetition of the Amida is followed by אָבִינוּ מַלְכֵּנוּ in most communities, followed by Tachanun, Kaddish and עָלֵינוּ .
