REDEEMING RAINBOW QUOTE

When googling "redeeming rainbow", this article(http://www.chabad.org/magazine/article.asp?AID=432583) pops up with the below paragraph:

"Whenever mankind's skies would darken with untoward deeds; whenever the tapestry of humankind's collective performance would grow heavy from sinful pursuits; when their atmosphere would roll and their world would crash with the thunder of violence and the turbulence of injustice; when dreadful flashes of denial, dishonesty, cruelty and depravity would rend society asunder; when the victims' blood and the tears of the oppressed would fall in hopeless torrents and disappear beneath the sullen sodden soil of man's conscience --there would yet appear a redeeming rainbow."

-Yaakov Paley
