Yesterday at http://www.fivedoves.com/letters/oct2010/nancyh104.htm Nancy asked about Rosh Hashanah.  I sent in a post about a month ago on this topic that is still archived at http://www.fivedoves.com/letters/sep2010/jovial98-1.htm that shows that the term "Rosh Hashanah" actually does appear in Scripture and it's usage there helps us understand a multitude of things about the correct and incorrect usage of that term.
