In the beginning... God created 7's.

Oh sure, He created light and dark, the heavens and earth, too. But for reasons unknown to us, He seemed to have a special affinity for the number 7.

The fact that the Torah begins with a verse containing 7 words and 28 letters (divisible by 7) is hardly remarkable. But when placed within the context of the overwhelming number of associations in Judaism with '7', a fascinating tapestry begins to unfurl. Let's take a closer look at this phenomenon.

WHY "SHAVUOT?"

Every spring, Jews around the world celebrate the holiday of Shavuot --commemorating the most seminal event in the history of mankind, God's revelation at Mount Sinai.

Shavuot. Curious name for this holiday, no? Shavuot means "weeks," underscoring the 7-week period between Passover and Shavuot in which we count each day (and week) in anticipation and preparation for re-living the Sinai revelation. But why call it Shavuot -- "weeks"? Why not call the holiday "Torah," or "Sinai," or "Commandments," or "Tablets." Of what significance is "Weeks"?

Time contains many different entities. Nearly all of them are related to natural phenomena. Days, nights, months, seasons and years are all directly determined, in some way, by the constellations. There is one exception -- the week. The formulation of a week seems to be totally arbitrary. Who needs it? Let one day just follow the previous one. And why 7 days?

The concept of a week and its constitution of 7 days is one that is strictly God-invented and human-adopted. While we may quibble about creation -- how, when, by whom, why -- the world has consensually agreed to the concept of a week. The Beatles were wrong... there are only 7 days in a week. And whenever a week is completed it is yet another reminder to mankind (or should be) that God created the world in 7 days. (Only 6 days were required to manufacture the physical structures, but the process was not complete until the spiritual realm, Shabbat, was added.)

Call it the "week link."

WHY "7"?

Kabbalah teaches that 7 represents wholeness and completion. After 7 days, the world was complete. There are 6 directions in our world: north, south, east, west, up and down. Add to that the place where you are, and you have a total of 7 points of reference.

Shavuot, marking the emergence of the Jewish people into a nation, by virtue of their receiving and accepting the Torah, also marks a completion. Perhaps that is why the holiday is called Shavuot, "Weeks." We want to identify this holiday as a completion of the process of Jewish nationhood.

No one is certain why God chose the number "7" to signify completion. All we can do is speculate, observe and marvel.

In honor of our own completion of the 49 day period leading up to Shavuot, we present 49 allusions to the number "7" within Judaism. How many of these do you recognize? How many more can you add?
