Nevertheless, a great many people use this phrase out of context in the wrong sense described above, when responding to, or rather just commenting upon, some criticism made by someone perceived as part of the group, e.g. an Israeli voicing allegedly unpatriotic opinions, or a Jew expressing, heavens forbid, support for the cessation of racial discrimination in Israel, etc. That phrase is used, often as the sole content of the message, often with a high and mighty air, as in "as is written in the Bible..."
This really bugs me. Today, an article ygurvitz linked to (in Hebrew) received a reader comment with this phrase as title and as the final sentence of the (long) comment itself. Ugh. So it finally bugged me enough to put up a short Web page explaining this (Hebrew). I hope it will eventually be noticed and linked to by people in whose face this phrase is thrust -- quoting the bible out of ignorance can and should be exposed and discredited.
The things that push my buttons... :)
