In Jewish tradition, a tzaddik is someone who dies on Rosh Hashanah …
and is “a person of great righteousness”
(the quality of being morally right or justifiable).

This night, shofars were blown outside in many communities,
signalling the start of the Jewish celebration, Rosh Hashanah

And this night, Justice Ruth Bader Ginsberg, of the Supreme Court of the United States,
faithful adherent of Judaism, died.
Tzaddick.
I think this fits RBG well.

May those who are marking Rosh Hashanah at this time,
discover a new sense of possibility,
a new belief in the hope that RBG’s legacy will not end,
and a renewed commitment to their beliefs and dreams.
Happy Rosh Hashanah!

And may she, of blessed memory,
be lovingly remembered and respected
by people of all nationalities, religions, political beliefs.

Rest in peace, Supreme Court Justice and tzaddik, Ruth Bader Ginsberg.
Rest in peace.
