On Shabbat Noach -- having read, this morning, the verses wherein God promises Noah and his sons that the rainbow is the sign that God will never again destroy the world with flood -- I can't resist posting this photo, taken in Paris a few days ago:

Rainbow over the Left Bank.

(If you're looking for a good reading for this week's parsha, I recommend Reb Arthur Waskow's Rainbow Covenant Haftarah -- in bilingual pdf here, in English here.)
