Who knows two hundred seventy?

Please cite/link your sources, if possible.

At some point between twenty-four hours and a few days from now, I will:

  • Vote up all interesting, relevant answers.

  • Accept what I consider the "best" answer.

  • Move on to the next number.

To those who like this series, sorry about the hiatus.

Lazy gematria for today is either awake or bad.

  • Being new to this series, I'm wondering, just how far can we stretch the number? Gematria? At-Bash? Achas-Betah? English calendar years? abbreviations?

    @HodofHod, people have done all sorts of things. Personally, I don't like gimatriyaos unless they are sourced (by e.g. the Baal Haturim, i.e., don't just find some word that happens to have the right gimatriya), but I know others differ. I personally have answered one or two of these with Christian calendar years, but really didn't like to, and I seem to recall those answers didn't get many up-votes. But do what you want, I guess, and glean from the votes and comments how much people like them, for future reference.

As mentioned in this answer:

The Chinuch calculates that there are 270 Mitzvot (48 Positive and 222 Negative) that are always applicable during exile, without needing a specific situation in order to obligate oneself (there are an additional 99 that are also applicable during exile, but only situationally). The mnemonic for this is "‫אני‬ ‫ישנה ולבי ע״ר‬" [I'm asleep but my heart is awake - in other places it explains that this refers to exile, that even while in a state of sleep (i.e. exile) we still do (at least) 270 Mitzvot]


Wow, this is tough! ummm.... Number of Synagogues in the US in 1880? http://www.spartacus.schoolnet.co.uk/USAEjews.htm


The big earthquake in Turkey in August of 1912 destroyed 270 "Jewish houses" (presumably houses of Jews) in Gallipoli, according to The American Jewish Year Book.


Gabriel Wilensky reports that there was a 1421 decree against Jews issued in Vienna which resulted in the burning of 270 Jews, הי״ד, at the stake.


Wikipedia's article on the number 270 says that it is the average number of days in a human pregnancy. If "tisho yarchei leido" was good enough for echod mi yodeya ....

    I haven't been able to find any other sources corroborating this number. Most either give a range or say 280 (= 40 weeks).

    So you're... taking the number modulo 1000 and rounding it to the nearest 10.
