Ten types of tum'ah (impurity) that can originate from a person (Mishnah, Kelim 1:5).

And more positively, ten levels of spatial kedushah (sanctity), beginning with the Land of Israel and ending with the Holy of Holies in the Beis Hamikdash (ibid., 1:6 and following mishnayos).

    Better translation than "tests." – Isaac Moses Mar 28 '10 at 21:56
  • @IsaacMoses - Why? – Adam Mosheh May 4 '12 at 16:18
  • 1
    @AdamMosheh, because "test" generally implies that the one applying it is trying to learn something. As the One applying these was the Omniscient, that could not have been the purpose. – Isaac Moses May 4 '12 at 16:21

The world was created with ten statements.


Ten Sefirot (total!)

  • True no matter what way you count them! (Sefer Yetzirah) – Yahu Apr 8 '10 at 0:11
  • @Yahu - What do you mean by that? And where does teh Sefer haYetzirah say that? – Adam Mosheh May 30 '12 at 20:58
  • 2
    @AdamMosheh I imagine he means that sometimes kabbalists include Keser instead of Daas, and vice versa. Either way, it's still ten. The quote from Sefer Yetzirah is (I imagine) Ten sefirot of nothingness; ten and not nine, ten and not eleven. Where in Sefer Yetzirah it is probably depends on which edition you have. – Hod - Monica's Army May 31 '12 at 0:02

    Is there any significance to this? There's also 12 times where you find טט in one word, 8 times where there is עע in one word, and 937 where you find יי in one word. – Double AA Jan 15 '13 at 18:43
  • @DoubleAA Need there be significance? I don't remember that being a requirement in the OP. – ezra Jan 26 '18 at 3:46
  • @ezra It is explicit in the newer MY Series posts. But even if it's not literally required, it's clearly stupid to make a list of insignificant 10s... – Double AA Jan 28 '18 at 21:09

10 are the words in the blessing Hamotzi.

Number of words used to count a minyon in Tehillim 28:9

הוֹשִׁיעָה אֶת עַמֶּךָ וּבָרֵךְ אֶת נַחֲלָתֶךָ וּרְעֵם וְנַשְּׂאֵם עַד הָעוֹלָם

  • Add explicitly that it is used to count a minyon (number of words in tehillim 28:9) – sabbahillel Apr 21 '16 at 18:18
  • @sabbahillel Any source for this? – Kazi bácsi May 22 '18 at 15:05
  • @Kazibácsi just from having been in shul when it is used to count. – sabbahillel May 22 '18 at 20:20
  • @sabbahillel An elderly person taught it to me long ago, but it'd be nice to find a source. – Kazi bácsi May 22 '18 at 21:02

Ten is the number of the Lost Tribes of Israel, who were exiled to Assyria because of their misdeeds. (II Kings 17:6)

The Talmud (Sanhedrin 110b) brings several opinions concerning the eventual fate of these tribes. According to Rabbi Akiva, they will never return. According to Rabbi Eliezer, they will indeed return to the Land of Israel eventually. In the view of Rabbi Shimon ben Yehudah, the fate of the tribes depends on whether or not they repent.

The entire daf is quite interesting; I'd suggest looking at it for further reading.


Ten are the kosher mammals:

שׁ֕וֹר שֵׂ֥ה כְשָׂבִ֖ים וְשֵׂ֥ה עִזִּֽים׃ אַיָּ֥ל וּצְבִ֖י וְיַחְמ֑וּר וְאַקּ֥וֹ וְדִישֹׁ֖ן וּתְא֥וֹ וָזָֽמֶר׃


10 - are the principles that the Torah requires to effect a halachik divorce (Rambam, Hilchos Geirushin 1:1).

  • 1) That a man must voluntarily initiate the divorce. (ibid 1:2)

  • 2) The method of divorce must be done in writing and nothing else. (ibid 1:3)

  • 3) That subject of the get must make clear that the husband is divorcing his wife and releasing her from his domain. (ibid 1:5)

  • 4) The essence of the text of the get should express the severing of the connection between the husband and wife. (ibid 1:3)

  • 5) That get must be written l'shma- ie specifically for her. (ibid 1:3)

  • 6) After the get is written, it must not require any other action except delivery to the woman (For example: writing a get on the horn of a cow and then detaching said horn and giving it as a get would be invalid). (ibid 1:6)

  • 7) The husband must give/ transfer over the get to her. (ibid 1:3)

  • 8) The husband must give her the get in the presence of witnesses. (ibid 1:13)

  • 9) The husband must give her the get for the sake of divorce. (ibid 1:9)

  • 10) The husband or his agent must be the one who gives her the get. (ibid 1:3)

(the rest of the requirements of a get- ie the date, the signature of the witnesses, etc- are all mi'drabanan)
