100 times ש״ם is written in Tehillim.

share|improve this answer
האמנם? It appears over 100 times just in the first 20 chapters of Tehillim. Maybe the Megaleh Amukos means that the word שם, in all of its conjugations, appears 100 times? – Alex Oct 6 '10 at 20:03

100 is the g'matriya of "מדון" (Rashi, Sanhedrin 7a).

share|improve this answer

100 is the number of people Elisha fed with a small amount of food (M'lachim II 4:43). (I haven't checked the commentaries, so it could be that this is an example of the hyperbole mentioned above, but I doubt it. Note that Rabbi Aron Tendler seems to say it really means 100.)

share|improve this answer
Also the Gemara seems to assume that it's literal, because it uses this to calculate that Elisha had 2200 full-time students (Kesubos 106a). – Alex Oct 7 '10 at 20:16

100 was Shem's age (in years) when his son Arpachshad was born (B'reshis 11:10).

100 is a number used as an example of a very large number in rabbinic Hebrew, as in Rashi to D'varim 15:10 and as in "דוחה מאה תוכחות".‎

share|improve this answer
We find it used in Biblical Hebrew too - in Eccles. 6:3, "אם יוליד איש מאה". – Alex Oct 7 '10 at 18:47

A paper, a different version of which was apparently published in the J. Hal. Contemp. Soc., quotes the Tzemach Tzedek (Lubavitch, not Nikolsburg) as saying that 100 amos (cubits) is the distance water must travel underground before it comes up again to be considered a spring.

Some blogger quotes the Ben Ish Chay as saying that Adam was 100 amos (cubits) tall — but I have no other source for that, myself.

share|improve this answer
Bava Basra 75a (R' Meir, who says that 200 amos is "twice the height of Adam"); Bamidbar Rabbah 13:12 (R' Yehudah). – Alex Oct 6 '10 at 20:01

share|improve this answer
The "lech l'cha" one is especially meaningful because of the midrash that Hashem was hinting to the fact that Avraham would have a son at 100: tsel.org/torah/yalkutsh/lechlecha.html – msh210 Oct 6 '10 at 15:04
And if we're counting random g'matriyaos, with nothing special about them, then there are bunch more: על,‎ ההנהלה,‎ היפה,‎ etc. etc. – msh210 Oct 7 '10 at 16:11

$100 is the threshold value a Rabbi of mine suggested for determining whether a new garment deserves a "Shehecheyanu".

(Interestingly, he suggested the same threshold over many years, apparently not taking inflation into consideration. Perhaps the psychological value of that round number retains significance across inflation.)

Difficult circumstances increase the value of Torah learning by at least 100x.

What to do if you're not sure if you remembered to say Mashiv Haruach U'morid Ha'geshem in sh'moneh esrei?

If you've already said it 100 times, (some say only 90), we assume that you remembered to say it and you do not repeat sh'moneh esrei.

share|improve this answer
And some say it takes 101, based on this: mi.yodeya.com/questions/3027/meya-mi-yodeya/3031#3031. There's also those who argue that it takes 90 days of actual real-use habituation, one long chant may not cut it. – Shalom Sep 28 '10 at 18:23
