Kezayit: Tu B'Shevat In A Nutshell

With Tu B'Shevat less than a week away, we're sharing another Kezayit feature here. What's this Kezayit thing? Read here.

This coming Monday, January 25, is Tu B'Shevat (literally translating as "the 15th of Shevat").

Prior to the destruction of the Second Temple in Jerusalem (in 70 C.E.), Tu B'Shevat was a fiscal and agricultural year turnover, the date on which Israelite farmers calculated what tree and fruit crop tithes they owed the Temple.

Once Jews were living in diaspora, however, the rabbis reconceived Tu B'Shevat as a minor holiday during which Jews recalled and celebrated their ties to the Holy Land. For 1,500 years, Tu B'Shevat was a relative blip on the Jewish holiday calendar. That began to change in the 16th century, when the date became a spiritual locus for Jewish mystics. Rabbi Isaac Luria and his Safed disciples created a Kabbalistic Tu B'Shevat seder that emphasizes spiritual nourishment of the Tree of Life. The language of the seder roughly maps the sephirot, the ten Divine Emanations of G-d according to Kabbalah, as a tree -- roots, trunk, branches, and leaves.

Fast forward another 300 years or so, and Tu B'Shevat was given yet another makeover. The Jewish National Fund began celebrating the holiday as a kind of Israeli Arbor Day, a way to raise public awareness of and international support for their afforestation campaign. Because of this new association, many Jewish Americans would come to think of Tu B'Shevat as a "Jewish Earth Day."

Today, Tu B'Shevat is growing in popular observance, and is flavored with a little bit of mysticism, a little bit of environmentalism, and a lot of nuts, olives, figs, and other tasty treats.

Oh, and apparently the holiday precipitated a rap song and video that's so embarrassing it's almost endearing. Click the screenshot below to subject yourself to three minutes of incredulity and aural vexation. Do it for the trees.
