Secrets of the Ten Plagues & the Passover Seder (Video)

What was the deeper purpose behind the Ten Plagues in ancient Egypt and how did they parallel the Ten Utterances of Creation? How do these correspond to the ten items of the Passover seder? And how do the 14 steps of the Passover seder parallel the 14 key steps of Creation? Find out in this eye-opening class where we also explore the paschal offering and the Temple Mount, how Hillel rose to the presidency of the Sanhedrin, plus the great mystery behind consuming the karpas vegetable – and what does it have to do with the soul of Mashiach?

The Kabbalah of Solar

This Friday evening, we usher in the new year 5784 of the Hebrew lunisolar calendar. Our calendar follows lunar months, but is synchronized to the sun over the course of a 19-year cycle. Since a lunar month is 29.5 days, each month on the Hebrew calendar is either 29 or 30 days, resulting in a year that is typically just 354 days long. The solar year is a bit over 365 days long, meaning that a strictly lunar calendar will fall behind 11 days each year. To avoid this problem, we add an entire leap month, a second Adar, seven times in 19 years. This ensures that we stay in synch with both moon and sun. The upcoming year will be such a leap year, with 13 months instead of 12.

Although our calendar is lunisolar, and Jewish holidays, rituals, and halakhot generally follow this calendar, there are exceptions to the rule. In fact, there are a handful of Jewish laws and principles that follow not the lunisolar calendar, but the solar calendar of 365 days! We will explore some of the major ones below, and then look at the Zohar’s incredible revelations about the secrets of the solar calendar. Continue reading

Secrets of Pi

This week’s conjoined Torah portions of Vayak’hel and Pekudei conclude the description of the Mishkan’s construction. The Haftarah for Pekudei is a passage from the seventh chapter of I Kings (the exact verses vary by community) describing King Solomon’s construction of the Jerusalem Temple. One of the most breathtaking structures standing in front of the Temple was the “Molten Sea”, a large bathtub for the kohanim to immerse in (as per Rashi and II Chronicles 4:6). The Tanakh describes that the bath was circular, sitting upon a base of twelve oxen statues, and had a total depth of five cubits, roughly ten feet. It held a volume of alpayim bat, “two thousand baths” of water (I Kings 7:26). In fact, the Hebrew bat (בת) is likely the etymology for the English word “bath”!

What’s most perplexing in the description is that we are told the diameter of the circular tub was 10 cubits, yet its circumference was 30 cubits. Throughout history, many have pointed out that this seems to be an error! We all know that the ratio of a circle’s circumference to its diameter is π or Pi, which is 3.1415926 (and so on). So, the Tanakh should have said that the diameter was 10 cubits and the circumference was 31 or 31 and a half cubits. How do we solve this puzzle, and what deeper significance does Pi hold in the Torah?
