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
@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!)

share|improve this answer
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
@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. – HodofHod 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

10 are the words in the blessing Hamotzi.
