From the grainy cell phone nature photography collection, a snapshot of a (very faint) double rainbow snapped on our trip to GA. (If you can’t see the 2nd rainbow, it’s more of a faint color smudge to the right of the first rainbow.)
From the Hebrew blessing upon seeing a rainbow (on a set of cards I carry in my bag):
Blessed are you, Creator of the Universe, who remembers the covenant, is faithful to it, and keeps Your promise.
(Based on the story of Noah’s Ark.)
