This week’s parasha, Tetzave, continues in describing the design of the objects used in the Mishkan, the Holy Tabernacle. The focus turns to the vestments of the kohen gadol. We see again that the most notable fibres used in sewing these clothes were tekhelet, argaman, and tola’at shani—blue, purple, and red wool. Our Sages taught (Menachot 43b) that tekhelet is sea-blue, and the sea reflects the sky, which is symbolic of God’s Throne, as per Exodus 24:10, where the nation saw that “there was under His feet the likeness of sapphire stone, and the likeness of clear skies…” (Similarly, Isaiah 66:1 has God declaring that “the skies are My throne, and the Earth is My footstool…”)
Among other things, blue is associated with water, which is in turn associated with life. In Kabbalah, blue is one of the colours of Chessed, lovingkindness. Red is its polar opposite, the colour of blood and fire, representing Gevurah, judgement and severity. Combining red and blue gives purple, the balance between them, Tiferet, seat of truth and beauty. On a mystical level, the purple argaman (ארגמן) also represents the chief angels Uriel (אוריאל), Raphael (רפאל), Gabriel (גבריאל), Michael (מיכאל), and Nuriel (נוריאל).
At first glance, the colours of the three key Sefirot of Chessed, Gevurah, and Tiferet appear to be blue, red, and purple, respectively. However, this is not always the case. In varying sources, the colours of the Sefirot are presented differently. While it is undoubtedly true that in Judaism multiple opinions can be correct simultaneously, can we nonetheless put together a definitive colour spectrum for the Sefirot? Today, we have a great deal of scientific knowledge of light and colour that can greatly assist us in this endeavour. So, which colours correspond to the Sefirot? Continue reading →
This week’s parasha is Beshalach, with its climactic moment being the Splitting of the Sea. Before this, we are told that “God went before them by day in a pillar of cloud to lead them the way; and by night in a pillar of fire to give them light, so that they could journey day and night.” (Exodus 13:21) The Zohar (II, 46b) comments on this that the Patriarchs travelled alongside Israel: the words “went before them by day” refers to Abraham; “in a pillar of cloud” is Isaac; “to lead them the way” is Jacob; “by night in a pillar of fire to give them light” is David. The Zohar then says that these four are the faces upon God’s Holy “Chariot”.
It is the prophet Ezekiel that describes the Chariot in greatest detail. The Book of Ezekiel begins with his famous vision:
And I looked, and, behold, a stormy wind came out of the north, a great cloud, with a fire flashing up, so that a brightness was round about it; and out of the midst thereof as the colour of electrum, out of the midst of the fire. And out of the midst thereof came the likeness of four living creatures. And this was their appearance: they had the likeness of a man. And every one had four faces, and every one of them had four wings… As for the likeness of their faces, they had the face of a man; and they four had the face of a lion on the right side; and they four had the face of an ox on the left side; they four had also the face of an eagle.
Each of the four corners of God’s Chariot has an angel “driving” it. As might be expected for a chariot, beneath each angel is a spinning wheel. The description appears to be speaking not of a simple wheel, but possibly a gyroscope, a “wheel within a wheel” as Ezekiel states (1:16). Each angel has four faces: the face of a man at front, a lion at right, an ox on the left, and an eagle on the back. Understanding the appearance of the animal faces is straight-forward, but whose human faces adorn the angels? The Zohar states these are the faces of God’s beloved Abraham, Isaac, Jacob, and David.
The “Tree of Life” depicting the Ten Sefirot, intertwined by the 22 Letters of the Hebrew Alphabet. Together, they make up the 32 Paths of Wisdom.
Recall that Abraham represents the Sefirah of Chessed, “kindness”; Isaac represents Gevurah, restraint and judgement; Jacob is Tiferet: beauty, balance, truth; and David is Malkhut, “kingdom”. These four Sefirot also correspond to four elements: Chessed is flowing, life-giving water; Gevurah is powerful, burning fire; Tiferet is the spirit of boundless air; Malkhut is the earthy kingdom below. Although there are, of course, Ten Sefirot, these four in particular serve as the major “axes” of the Tree of Life. They have also been said to correspond to the three major dimensions of space, and the fourth dimension of time. (It is worth mentioning that string theory has expanded the number of dimensions to ten—as we might have predicted all along based on the Sefirot!)
Each of the Chariot faces also parallels the major constellations of the Zodiac: first is dli, “Aquarius”, with the face of a human. Three months later comes shor, “Taurus”, the bull or ox. Three months after that is aryeh, “Leo”, the lion. Finally, after another three months is ‘akrav, “Scorpio”, which in ancient times was alternately referred to as the “Eagle” constellation, nesher. The Zohar (I, 24a) points out that the initials of these four constellations and their faces is shinan (שנא״ן), standing for shor, nesher, aryeh, and the nun sofit being representative of the complete human. This is the meaning of the cryptic statement in Psalms (68:18) that “God’s Chariots are myriads, alfei shinan; God is among them, as in Sinai.” Just as at the Splitting of the Sea and at the Divine Revelation at Mt. Sinai that followed, when God “descended” into this world amongst myriads of Chariots, He continues to “mount the Cherubs and fly, gliding on the wings of the winds…” (Psalm 18:11)
The Talmud (Avodah Zarah 3b) offers another mystical meaning of alfei shinan: that God “rides” through 18,000 worlds. This number is derived from the fact that the verse states the number of Chariots is ribotaim, meaning “twenty thousand”, but then says alfei shinan, which can mean “less two thousand”. So, twenty thousand less two thousand leaves 18,000! What are these 18,000 worlds through which God “rides”? The Zohar (ibid.) states that these are the worlds in which God’s Presence dwells. If His Presence dwells there, it implies that there is someone in those worlds to benefit from His Presence! Incredibly, one of the most ancient Jewish mystical texts, Seder HaRuchot, says that God visits these 18,000 worlds and “examines their populations” in an instant! Based on such sources, there have been authorities who’ve suggested there very well may be life on other planets—perhaps 18,000 of them out there in the vastness of the cosmos. Generally speaking, these 18,000 are thought to be strictly angelic worlds, inhabited by the supernal beings. (For a lot more on this, see here.)
While each forefather may have excelled in one particular aspect, he was also a complete man who possessed the other traits. Abraham was mainly Chessed, but clearly displayed Gevurah, too, as we see in harsh trials like the Akedah. The Torah says three times that Abraham arose early in disciplined service of God (Genesis 19:27, 21:14, 22:3). Meanwhile, Isaac was Gevurah first and foremost, but is also described with words of lovingkindness in at least three places (Genesis 24:67, 25:28, 27:9-14). Jacob is the perfect balance of the two, hence it is Jacob that embodies the balance and truth of Tiferet. And David is the very reflection of Jacob centuries later. One who reads the Tanakh carefully will see how the lives of Jacob and David mirror each other. (For more on this, see ‘The Mystical Connection Between Jacob and David’.)
This is one reason why each of the faces of the Patriarchs on the Chariot also had a lion, ox, and eagle face. When necessary, each of these great Jewish figures could “put on” their lion face, representing Gevurah, and fight noble battles. [In fact, the gematria of “lion” (אריה) is 216, equal to Gevurah (גבורה)!] At other times, they could be the “ox” peacefully tilling the soil and investing in the development of the Holy Land. As we read in the Tanakh, each of the four figures did tremendous work in the Holy Land, from digging wells to planting trees (and everything in between) in order to make the land flourish and prosper. They could also put on an “eagle” face and “hover over their hatchlings” (Deuteronomy 32:11). The eagle has to teach its chicks some perilous skills like flying and hunting. The figures of the Chariot similarly taught their families and disciples how to navigate the dangers of this material world and live the proper spiritual path. (The Arizal has a fascinating discussion on the eagle and its ability to spot and defeat the snake—symbolic of the evil inclination—in Sha’ar HaPesukim on Mishlei.) Their teachings continue to give us the tools to fly ever higher today.
There is a wonderful lesson here for us. Every good human being works hard like an ox, hovers over their family like an eagle, and defends them like a lion. Behind the face of each person—like the face of each Patriarch, and the face of each angel on God’s Chariot—is the face of a lion, an eagle, and an ox. The spinning wheels beneath these faces symbolize the need to put on a different one of these faces at different times, when the situation calls for it. We have to be able to display both kindness and strength, both beauty and modesty, humility and honour. We must balance all the elements—water, fire, air, earth—within us, and walk the spiritual trail blazed by Abraham, Isaac, Jacob, and David. This is the “pillar of fire” that guided and protected the Israelites in the Wilderness, and continues to guide us and protect us today.
This week’s parasha, Vayetze, begins with Jacob setting forth towards his mother’s hometown in Haran. We read that on his way he suddenly “bumped into” a special place (Genesis 28:11) that turned out to be Beit El, the “House of God”. Jacob was surprised to find himself there (28:16), presumably the site of the future House of God, the Temple in Jerusalem. The Sages (Sanhedrin 95b) explain what happened:
“And Jacob went out from Be’er Sheva, and went to Haran…” is followed by “and he happened upon the place, and tarried there all night, because the sun was set.” For when he reached Haran, he said: “Shall I have passed through the place in which my fathers prayed, without doing so likewise?!” He wished therefore to return, but no sooner had he thought of this than the earth instantly contracted and he “happened upon” that place.
Our Sages state that a miracle occurred after Jacob had reached Haran. He regretted not stopping by at the site of the future Temple Mount, where Abraham and Isaac had prayed, so the earth beneath his feet seemingly “contracted” and he was suddenly teleported to Jerusalem. In fact, the Sages state that such a miracle occurred for three people in the Tanakh: first was Eliezer, Abraham’s servant, then Jacob in this week’s parasha, and finally King David’s general Avishai. There is Scriptural proof for each one. For instance, when Eliezer had arrived in Haran he declared “I came today to the well” (Genesis 24:42), implying he had set out on his journey that same day. Eliezer was miraculously able to go from Be’er Sheva to Haran, a significantly long journey, in under a day.
This phenomenon would later become known as kefitzat haderekh, “jumping the path”, and would appear in Rabbinic narratives as well. Angels have a similar ability to seemingly teleport across vast distances. In one story, Rav Kahana was once selling some wares and a female customer tried to seduce him (Kiddushin 40a). He quickly fled in distress and ran to the nearest window and jumped! The angel-prophet Eliyahu appeared and caught him, complaining that he had to instantly travel a distance of “four hundred parasangs” to save him. A parasang, or parsa, is the average distance a person walks in 72 minutes—generally thought to be about 5 kilometres. So, Eliyahu flew some 2000 kilometres in a flash to catch the rabbi. Rav Kahana apologized and lamented that due to his poverty he had to resort to being a salesman. Eliyahu gave him a vessel full of money to free him from his job.
Meanwhile, the Zohar (I, 4b-5a) states that the malevolent angel Samael can traverse as much as 6000 parsas in a single moment. This number is not arbitrary, for the Talmud calculates that the Earth’s circumference is 6000 parsas (Pesachim 94a). This is an incredible piece of Talmudic science, considering how little of the globe was known then. Today, we know that Earth’s exact circumference is 40,075 km at the equator, a value close to that of our Sages. In fact, if making the correct assumption that the Sages must have been exact in their knowledge, we might be able to properly identify the length of a Talmudic parsa.
Although it is generally calculated in halakhah that a parsa is between 4 and 5 kilometres, by dividing 40,075 km by 6000 we can conclude that a parsa must be closer to 6.68 kilometres. This is also more in line with the notion that a parsa is a distance of 72 minutes: The average walking speed of humans is 5 km per hour (1.42 metres per second, according to the most precise measurements), so defining a parsa as 6.68 km is much closer to the scientific reality.
Jacob’s Ladder through Spacetime
The Talmud (Chullin 91b) calculates that the distance of the Heavenly Ladder that Jacob saw in his vision was a whopping 8000 parsas, which would be over 50,000 km. The word used by our Sages is rochav, meaning “width”. A superficial reading of the Talmud suggests that each angel is 2000 parsas wide (based on Daniel 10:6), and since Jacob saw four angels, the width of the Ladder must have been 8000 parsas. However, this does not make sense if taken literally, for why would an angel’s form be 2000 parsas wide? And if it was, how could Jacob even capture the sight of an angel in his limited field of view? The Talmud must be teaching something else. The big question here is why use the language of width as opposed to length or height, as might be expected?
When it comes to understanding the cosmos, we always speak of a “fabric of spacetime”. Perhaps the greatest achievement of Albert Einstein is pioneering the science behind it, proving that the three dimensions of space and the dimension of time are not separate, but interwoven together. With this, he was able to explain gravity a lot more accurately, demonstrating that larger bodies make a bigger “dip” in the fabric, pulling objects towards them kind of like a penny rolling around a funnel. And because they are integrated, strong gravitational effects can warp both space and time. We typically visualize spacetime as a flat “fabric”, with celestial objects scattered all over it. In fact, today we know that the universe does indeed appear to be flat (with a margin of error of about 0.4%). This is of tremendous significance.
In the Torah, the term aretz can refer to both Earth proper, and the wider physical universe at large. When we read that in the beginning God created et shamayim v’et ha’aretz, we do not define it simply as the “sky” and the “earth”, for those were not created until Days Two and Three. Rather, God created the entire spiritual realm (shamayim) and the entire physical universe (aretz). Our Sages noted long ago that the root of aretz (ארץ) is the same as ratz (רץ), “running”, since everything in this universe is in perpetual motion. More incredibly, today we know that the universe is constantly expanding, and we see distant stars “running away” from us. As such, when the Tanakh uses an idiom like kanfot ha’aretz, the “corners” or “edges” of the universe, it may be read quite literally. For a long time, there were people who understood these Torah statements as implying a flat Earth, when in reality they could have been alluding to a deeper scientific understanding regarding the “flatness” of the entire universe.
And that brings us back to the precise Talmudic language of rochav, “width”, in a place where we might have expected height. Of course, we do have a dimension of height. However, when zooming out to a “flat” universe, we really only visualize it in terms of width, as if on a two-dimensional plane. Going further, Einstein later showed, together with another Jewish scientist named Nathan Rosen, that it would be theoretically possible to “bend” spacetime and connect two points that are vastly far apart. It would be like folding over the fabric and then poking a hole through both layers. Such an “Einstein-Rosen bridge”, better known as a wormhole, would allow travel across extremely vast distances in a very short period of time. In other words, it would be very much like kefitzat haderekh!
A wormhole shortens the trip by bending spacetime and forming a bridge.
So, what our Sages may have been secretly implying in describing the width of Jacob’s Ladder is that this wormhole (of sorts) spanned 8000 parsas, or over 50,000 km. This is a distance even wider than the Earth and, scientifically, we would expect wormholes to be very large like this. Such a wormhole was accurately depicted in the film Interstellar, allowing the protagonists to instantly travel to a distant solar system to find a new home for mankind:
It is worth noting that when our Sages described the teleportation of Jacob, they said that kaftzah ha’aretz, again using that term aretz, and implying that it “jumped” or “contracted” for him. So, another term for this phenomenon, truer to the language of the Talmud, would be kefitzat ha’aretz, the warping of the spacetime fabric of this universe. Kefitzat haderekh is accurate, too, implying that one “jumped the path”, finding an alternate shortcut from one point in the universe to another. This appears to have happened at Sinai, as well. Our Sages likened Jacob’s Ladder to the Sinai Revelation, and the Zohar (I, 149a, Sitrei Torah) even notes that the numerical value of “ladder” (סלם) and “Sinai” (סיני) is the same—130. At Sinai, too, a “wormhole” opened up allowing 22,000 angelic “chariots” to descend upon the mountain (Bamidbar Rabbah 2:3).
Theoretical physics aside, can we actually create such wormholes? In 2017, scientists succeeded in producing tiny, microscopic wormholes for the first time. It is certainly possible that in the near future we will have the technology to open up larger wormholes, making rapid travel across God’s vast universe feasible. It appears that God’s angels already employ such a wormhole-style system of travel, traversing thousands of parsas instantaneously. It might help explain the Tower of Babel episode which, as we’ve mentioned in the past, was not simply a tower but meant to “lift off” and “conquer” the Heavens.
Our Sages long ago taught that the people who built the Tower knew the wisdom of the angels and were using angelic powers to accomplish their plans (see, for instance, Zohar I, 76a). God “came down” to confound them. He wiped their memories and jumbled their languages so that they wouldn’t be able to collaborate in such a megalomaniacal way. Today, we live in a world that is once more getting real close to being “of singular language and singular words” (Genesis 11:1), and once again we see science stepping into the dangerous territory of “playing God”. Hopefully this time humanity will get it right and use the astounding abilities that God made possible in His universe only for the good.
