Revision: It looks like we're probably not going to make it to 100, but the bonus points are still on the table. Any ideas for how I should award them? –  Isaac Moses Oct 6 '10 at 14:22

Maybe let them be autoawarded. I suspect there are many more Jewish hundreds no one's thinking of. –  msh210 Oct 6 '10 at 14:43

Yeah! If we can't reach 100, we don't deserve 100 points![/drill sergeant voice] –  msh210 Oct 6 '10 at 19:03

In the second בית המקדש, the היכל building (including the אולם) was 100 אמות tall by 100 אמות long by (at its widest point) 100 אמות wide. (Does that count as three on the list?) (Source: mishnayos Midos.)

One HUNdred are the ZUZ in A man-EH.

(Fits the beat.)

The Gemara points out the Hebrew word for widow, "almanah", sounds a lot like the "maneh" she receives for her ketubah.


Gen. 42:13

ויאמרו, שנים עשר עבדיך אחים אנחנו בני איש-אחד--בארץ כנען; והנה הקטן את-אבינו היום, ו*האחד* איננו

The words בנימן and האחד appear 100 times (each) in Tanach.

It was said by a play on words that R' Moshe Feinstein's native city, Starobin, had "one hundred rabbis" (in Russian, "sta rabin") - in other words, one hundred laymen (baalei batim) who were fully knowledgeable enough that they could have served as community rabbis elsewhere.

Why it's called Mea Shearim: It says that Yitzchak sowed the land and got 100 times the amount (en.wikipedia.org/wiki/Mea_Shearim) –  yydl Sep 28 '10 at 2:27

Right "100-fold." Many people think there's something about a hundred gates, different use of the word "shaar." –  Shalom Sep 28 '10 at 18:21

In Sefer Ner Lemeah R' Yerachmiel Zeltzer collected 100 answers (IY"H by us) to the following question:

In the Chanuka story, given that the oil would naturally have lasted for one day, wasn't only the continued burning on the second through seventh days miraculous, and shouldn't we therefore only celebrate for seven days?

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.

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

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

$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.)

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

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

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.

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.
