Nine are the total number of Cities of Refuge to be designated in the Land of Israel, when its boundaries are broadened (Deut. 19:9).

Incidentally, Maimonides (Laws of Kings 11:2) uses this verse as one of the proofs that the Torah speaks of a future era of Moshiach (may he come soon!), since the broadened boundaries of which this verse speaks have never yet come to pass, "and G-d did not give a command in vain."

  • Checkmark for fusing the number, halacha, derash, and an appropriate thought for the impending Shabbat and holiday, with sources! – Isaac Moses Mar 26 '10 at 15:40

There are 9 places in Tanach where the letter "ב" comes 3 in a row in the same word.

1 - Melachim2 25:28 - בבבל

2 - Yeshayahu 48:14 - בבבל

3 - Yirmiyahu 29:22 - בבבל

4 - Yirmiyahu 51:44 - בבבל

5 - Yirmiyahu 52:32 - בבבל

6 - Zecharya 2:12 - בבבת

7 - Ezra 5:17 - בבבל

8 - Ezra 6:1 - בבבל

9 - Divrei HaYomim2 36:7 - בבבל


... is what you get if you add up every three letters of the Alef Beis (for that matter any three numbers according to the numbering of the Alef Beis) if you start from Beis:

2+3+4=9, 5+6+7= 18 and 1+8=9,

8+9+10=27 and 2+7=9, etc.

If you don't believe me figure the rest for yourself!

9 - is the number of Parah Adumahs that have existed-- and utilized for ritual purposes-- thus far in Jewish history.

The mishna in Maseches Parah 3:5 lists these 9 Parah Adumahs:

  • 1) משֶׁה

  • 2) מֵעֶזְרָא

  • 3) שִׁמְעוֹן הַצַּדִּיק (did 2)

  • 5) וְיוֹחָנָן כֹּהֵן גָּדוֹל (did 2)

  • 7) אֶלְיְהוֹעֵינַי בֶּן הַקּוֹף

  • 8) וַחֲנַמְאֵל הַמִּצְרִי

  • 9) וְיִשְׁמָעֵאל בֶּן פִּיאָבִי

The Rambam in Hilchos Parah Adumah 3:4 codifies this number...

וְתֵשַׁע פָּרוֹת אֲדֻמּוֹת נַעֲשׂוּ מִשֶּׁנִּצְטַוּוּ בְּמִצְוָה זוֹ עַד שֶׁחָרַב הַבַּיִת בַּשְּׁנִיָּה. רִאשׁוֹנָה עָשָׂה משֶׁה רַבֵּנוּ. שְׁנִיָּה עָשָׂה עֶזְרָא. וְשֶׁבַע מֵעֶזְרָא עַד חֻרְבַּן הַבַּיִת

The second was done by Ezra. Seven more parah adumahs [existed] from Ezra until the destruction of the second Beis Hamikdash.

... before concluding that IH one day, b'mheirah b'yameinu:

וְהָעֲשִׂירִית יַעֲשֶׂה הַמֶּלֶךְ הַמָּשִׁיחַ מְהֵרָה יִגָּלֶה אָמֵן כֵּן יְהִי רָצוֹן:

And the tenth will be prepared by the Melech HaMashiach; may he speedily redeem us. Amen, may it be G‑d's will.
