100 is the number of prophets Ovadya hid from Izevel (M'lachim I 18:4).


$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.)


Im not sure what your looking for

יודעי = 100

  • This is a series that started with "Echad - mi yodeya?" mi.yodeya.com/questions/378/echad-mi-yodeya back when the site first went public on Rosh Chodesh Nissan. We've gone through 1 - 99, and we're up to 100 now. We're looking for answers to the question "Meya - mi yodeya" in the spirit of the Pesach song. – Isaac Moses Oct 3 '10 at 21:03

    In general, any Jewish facts about the number in question. – Isaac Moses Oct 4 '10 at 3:20

100 cc is a k'betza according to the Chazon Ish, IINM. (As always, CYLOR.)


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.)

    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

The Medrash Rabba in Parshas Mishpatim mentions that Kayin had 100 children.

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".‎


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