Editor's Note

By David Krantz


Seven is a holy number in Judaism. And, mathematically, each seventh represents about 14 percent of the total.


In Leviticus 23:15-16 and again in Deuteronomy 16:9-10, we are commanded to count seven weeks of seven days from Passover until the 50th day, Shavuot, the traditional anniversary of receiving the Torah. But that’s not the only time we’re commanded to count by sevens. In Leviticus 25:8-12, we’re told to count seven cycles of seven years — seven shmita, sabbatical, years until the 50th year, yovel, jubilee.


Think of yovel as a giant reset button, when mistakes are undone: Debts are forgiven, slaves are set free and wealth equality is restored. Yovel presents a blank slate and a second chance to get things right.


This Jewish Energy Guide consists of seven sections of seven articles, followed by a 50th, a jubilee, a vision for what life can be like by the time of our next yovel, if we will it. May we use this guide to help us prepare our second chance. Let’s reset our climate and restore the balance of greenhouse gases baking our planet, changing our climate and wrecking havoc on the human race.


May we be conscientious stewards of the Earth, and may we pass a healthier Earth on to our children and grandchildren. May we return to the days of old, when forests covered the land and fish filled the sea. May we breathe clean air and enjoy bright blue skies. And may the pages of this guide help lead the way.




David Krantz is the president and chairperson of Aytzim: Ecological Judaism, and the editor of the Jewish Energy Guide, published in partnership with the Coalition on the Environment and Jewish Life.
