Although the phrase seems to be more common among evangelical Christians these
days, its biblical origins and historical use are quite Jewish. for example,
<http://jwa.org/historymakers/szold/hadassah> tells the story of the "Daughters of
Zion" formed in New York in 1912, which in 1914 became the better known "Hadassah"
organization.

ps. the term "Messianic Jew" is a polite euphemism for "?Christian missionary".
