Mystery of the Shamir

This week’s parasha, Terumah, describes the construction of the mobile sanctuary, the Mishkan. While the Mishkan was designed to accompany the Israelites in their travels, the Haftarah for this week’s parasha describes how King Solomon finally built the permanent holy sanctuary in Jerusalem, the Beit haMikdash. The Haftarah tells us that the Temple “was built of stone finished at the quarry, and there was neither hammer nor axe nor any tool of iron heard in the house, while it was in building.” (I Kings 6:7) God did not permit the use of iron tools in constructing the Temple, for iron is an implement of war, and the Temple was a house of peace. So, how were the builders able to cut the stones without any iron tools?

The simplest explanation is that the stones were cut “at the quarry”, as the verse above states, and iron tools were only forbidden “in the house” itself. When God commanded not to use “hewn stones” for the altar (Exodus 20:23), it only meant not to cut the stones or bring iron tools directly onto the holy Temple Mount. The stones could, however, be cut elsewhere and brought to the Temple Mount. This suggestion is further supported by I Kings 5:31, where we read that “The king [Solomon] ordered huge blocks of choice stone to be quarried, so that the foundations of the house might be laid with hewn stones.”

Having said that, Jewish tradition holds that the stones for the Temple were cut entirely without the use of iron implements. Instead, our Sages teach that King Solomon had a unique tool called a Shamir, described as some kind of “worm” or “stone” that was able to penetrate even the toughest materials with laser-like precision. What, exactly, was the Shamir, and what might modern science reveal about this mysterious object?

Shamir in Tanakh and Talmud

The earliest source to mention the Shamir is the prophet Isaiah. In foretelling the destruction of Jerusalem, he said how the city “will be a desolation, it will not be pruned or hoed, and it shall be overgrown with shamir and thistles…” (Isaiah 5:6) This suggests that the Shamir is something organic and can grow. The notion is confirmed by the next source that discusses it, Jeremiah, who proclaimed that “The sin of Judah is inscribed with an iron stylus, engraved with tzipporen shamir…” (Jeremiah 17:1) Here we see the Shamir described as a tzipporen, loosely translated as a “fingernail” or “talon”. Again, it implies something organic, as opposed to the iron stylus it is juxtaposed with in the same verse.

We next see the Shamir in God’s message to the prophet Ezekiel, when He tells Ezekiel that He will make him like the Shamir, “harder than flint” (k’shamir chazak mitzor). Here we learn the Shamir is a substance of incredible strength. Rashi comments on this verse that the Shamir is a worm that splits rocks, or perhaps a type of hard flintstone, or even a particularly strong alloy of iron. The final direct mention of Shamir in the Tanakh is in Zechariah 7:12, where the nation is said to have hardened their hearts like the Shamir.*

Modern Rendition of the Choshen, the High Priest’s Breastplate

Next, we learn in the Mishnah that God created ten special, mystical things on the eve of the first Sabbath, at the very end of Creation (Avot 5:6). In this list is included the miracle-working staff of Moses, the Two Tablets of Law, and the Shamir. Rabbi Ovadiah of Bartenura (c. 1445-1515) comments here that the builders would draw a line on a stone, and the Shamir worm would crawl along the line and split the stone. He also points out that it was with the Shamir that Moses created the choshen and ephod, the Priestly Breastplate, and engraved the names of the Tribes of Israel into the precious stones on that breastplate. The source for this is the Talmud:

In Gittin 68a, we learn that Solomon was unsure of how to build the Temple without iron tools, and consulted with the Sanhedrin at the time. They told him: “There is a Shamir that Moses used to cut the stones for the ephod.” Solomon then asked the Sages where to find the Shamir, and this leads to a lengthy story about how he acquired it. (In fact, this is the longest story in the whole Talmud!) The puzzling narrative requires an in-depth analysis of its own, and is beyond the scope of the present discussion. Suffice it to say that it involves the great warrior Benayahu ben Yehoyada, a confrontation with Ashmedai, the “prince of demons”, and the angelic “Prince of the Sea”.

The Midrash (Yalkut Shimoni II, 182) has a slightly different account: Solomon knew how to speak to animals (I Kings 5:13), and he asked them where the Shamir might be found, at which point an eagle flew to the Garden of Eden and brought it to him! He then asked the Sages how to use the Shamir, and they directed him to Ashmedai. The Midrash also notes that the Shamir was so powerful it had to be wrapped in wool and kept in a special lead box filled with barley. The same teaching is found in the Talmud (Sotah 48b), too, where we also learn that the Shamir was the size of a barley grain, and that it ceased to exist following the destruction of the First Temple.

The big mystery is how the tiny Shamir, whether a “worm” or a “stone”, was able to penetrate hard substances and cut them with laser-like precision. While one could simply relegate this to a miracle, we generally hold that even God works through derekh hateva, natural ways, in most cases. Could there be a scientific explanation for the Shamir? Thankfully, our Sages left us a major clue that might help solve the mystery.

Shamir in Science

Our Sages taught that the Shamir had to be kept specifically in a box of lead to avoid danger. We have all probably received an x-ray exam at some point in our lives, and the technician always makes sure to put a lead jacket on the parts of the body not being scanned. This is because lead is an excellent blocker of dangerous radiation. This little detail strongly suggests that the Shamir was likely radioactive. Perhaps it used some kind of high-energy radiation to cut through stone. In fact, today we have nuclear-pumped lasers which use radioactive uranium fragments to create ultra-powerful light rays. Though such lasers are not commercially available at the moment, they have been proposed for use in manufacturing for precision deep-cutting and welding!

(Interestingly, renowned Jewish physicist Edward Teller, often called the “father of the hydrogen bomb”, proposed using such nuclear-pumped lasers in a space defense system that would shoot down enemy nuclear missiles. His “Project Excalibur” was soon scrapped and never realized.)

And then there’s the lithoredo. In 2019, scientists in the Philippines discovered a new species of shipworm, named Lithoredo abatanica. Unlike other shipworms which eat and bore into wood, the lithoredo eats and bores into limestone! They have special tiny teeth to grind away rock. Here is a worm that is actually able to eat through stone, and quite precisely, too. Could the Shamir have been a special version of the lithoredo, or a related species that is now extinct?

There is another tiny organism on the planet that is bizarrely able to withstand incredible conditions, including deadly radiation, dehydration, and even the freezing vacuum of outer space. This organism is the tardigrade, also known as a “water bear”. The hardiest creature on the planet, it can suspend its metabolism and literally go decades without any food or water at all. Uniquely, the DNA of tardigrades is protected by a special protein that blocks radiation, allowing them to survive levels of radiation hundreds of times greater than what would be lethal for humans. Could the Shamir have been some kind of special hybrid organism with qualities of both the tardigrade, capable of living many decades and withstanding immense radiation; and of the lithoredo, able to eat, digest, and cut through stone? Did the Shamir contain radioactive material in its body, or generate something laser-like? It is certainly within the realm of the scientifically-possible.

Ultimately, we may never know the true nature of the Shamir, for there are those who hold the future Third Temple will not require the Shamir in its construction. The Lubavitcher Rebbe, for instance, taught that since in the messianic era “swords will be beaten into plowshares” (Isaiah 2:4), iron will no longer be considered an implement of war and will therefore be allowed in the building of the Third Temple. Others hold that the Third Temple will not require building at all, and will descend fully-formed from the Heavens (see Rashi at the end of Sukkah 41a). Whatever the case might be, may we merit to see it speedily and in our days!

*For Marvel comics fans: the word shamir was translated into Greek as adamas, and then to Latin as adamans, and to English as “adamant”, the origin of “adamantium”, that super-hard element injected into Wolverine’s skeleton, and that made up the body of Ultron. (For more on Judaism and comic books, see here.) The Shamir was also the inspiration for the adopted last name of Israeli prime minister Yitzhak Shamir.

Secrets of the Star of David

Star of David on the 1000-year old Leningrad Codex (1008 CE).

This week’s double parasha is Vayak’hel-Pekudei, which speaks of the Sabbath, the construction of the Tabernacle, and the formal establishment of the priesthood. One of the things described is the creation of the Menorah. This seven-branched candelabrum is perhaps the oldest symbol of Judaism. We’ve discussed elsewhere how King David had the Menorah emblazoned on his shield (with the words of Psalm 67), and this was the famous magen David, “shield of David” (see ‘Secrets of the Menorah Psalm and the Jewish Holidays’ in Garments of Light.) Yet, strangely, the term magen David today is associated not with the Menorah symbol but with the “star of David”. Stranger still, this hexagram was historically known not as the “star of David” but rather as the “seal of Solomon”! Where did this symbol come from, what is its significance, and how did it become associated with the Jewish people?

Alchemy and Mysticism

Star of David in the Capernaum synagogue

The hexagram is a relatively simple shape and is found in art and architecture across Europe and Asia. While few ancient synagogues bear the star, many churches do. The most famous synagogue to have the star is the one discovered in 1866 in Capernaum (Kfar Nachum), a village on the Galilee initially founded by the Hashmoneans following their Chanukah victories. This synagogue is actually more popular among Christians, since the gospels of Luke and Mark describe how Jesus preached there. Archaeologists have also found the symbol on the seal of one Yehoshua ben Asayahu in the remains of the ancient city of Sidon. The seal is dated all the way back to the seventh century BCE.

Renowned scholar Gershom Scholem (see his Kabbalah, pgs. 362-368) pointed out that the hexagram was used by alchemists to represent the fusion of fire (the up-triangle) and water (the down-triangle). This may have a connection to a Jewish teaching on the meaning of the term oseh shalom bimromav, which describes God as making peace in the Heavenly realms. One explanation is that here in the lower world, water and fire are unable to co-exist, while up in the Heavens God is able to unify these opposing forces. This divine power was demonstrated with the seventh plague in Egypt, which was “hail with fire” intertwined (Exodus 9:24). The fact that it was the seventh plague in particular may be noteworthy, since the Star of David has seven parts: the six points of the star and the inner hexagon.

The three axes (x, y, z) of our three-dimensional reality, and the six faces (or six directions) that they produce.

That seven-based arrangement has a great deal of significance in Judaism. It represents Creation, with the six days of the week and the special Sabbath. This itself is a reflection of the fact that all physical things in this universe exist in three dimensions, ie. within a “cube” of six faces, while the seventh represents the inner, spiritual dimension. The same arrangement is found in the mystical Tree of Life, where the lower sefirot are arranged as six “male” qualities and the seventh, “female” quality (Malkhut). Because of this, the Arizal (Rabbi Isaac Luria, 1534-1572) arranged his Passover seder plate in a hexagonal style, with each of the components corresponding to one of the lower sefirot, while the three matzahs correspond to the higher sefirot (Chokhmah, Binah, Da’at), and the plate itself (or the cup of wine) paralleling the seventh and final Malkhut. 

The Pesach Seder Plate. There is a debate whether the Arizal intended the items to be placed in a star shape, or with two triangles one atop the other. The latter is likely as it more closely resembles the Tree of Life diagram.

This arrangement of seven (or more specifically, of three-three-one) is found within the Menorah, too, that most ancient of Jewish symbols. For this reason, some argue that the opinion of the Shield of David having the Menorah and the opinion of it having the hexagram are really one and the same. They both reflect a divine geometry of 3-3-1. The sefirot are arranged in the same 3-3-1 manner, and corresponding to them are the seven shepherds of Israel: Chessed, Gevurah, and Tiferet parallel the patriarchs Abraham, Isaac, and Jacob; Netzach, Hod, Yesod parallel the next three great leaders of Moses, Aaron, and Joseph; and Malkhut (“Kingdom”) naturally stands for David. David is at the centre of the star, so it is fitting that the star is named after him.

The first row of three (called by the acronym CHaGa”T), is followed by the second row of three (called NeHe”Y), and then the singular, “feminine” Malkhut (or Nukva), which receives from all the others.

Yet, it isn’t clear when and why the symbol became known as the “Star of David”. Rabbi Yirmiyahu Ullman points out that it may come from the fact that in Ancient Hebrew script the letter dalet has a triangular shape (much like the Greek delta), thus making “David” (דוד) appear as two triangles. Whatever the case, the symbol is already described as magen David, the “Shield of David”, in 14th century Kabbalistic texts, as Scholem points out. However, in those days it more commonly went by another name: the Seal of Solomon.

The Seal of Solomon

In medieval texts, the hexagram is most commonly referred to as the “seal of Solomon”. The earliest texts that mention it are actually Islamic texts, not Jewish ones. They speak of a special ring that King Solomon had which allowed him to interact with jinn spirits (the root of “genie”) both good and bad. Although the texts are Arabic, they are clearly based on more ancient Jewish teachings. In fact, the earliest reference to a special ring possessed by Solomon which allowed him to defend from evil spirits is in the Talmud.

In what is likely the longest story related in the Talmud (Gittin 68a-b), we are told of how Solomon sought to find the special shamir “worm” which would allow him to cut the stones for the Temple without using iron tools. He found the shamir’s whereabouts from the prince of demons, Ashmedai, whom he was able to subdue thanks to his special ring. In an incredible twist, Ashmedai gets a hold of Solomon’s ring and banishes the king from his own kingdom, turning him into a pauper, while Ashmedai himself took the throne impersonating Solomon! Thankfully, this “new” Solomon’s strange behaviour was soon noticed, and the real Solomon eventually made his way back to the palace to reclaim his throne, and his ring.

The Talmud does not state that the ring had a hexagram on it, but rather that it had God’s Name engraved upon it. It is Arabic texts that first connect the ring to the hexagram. Some attempt to distinguish between the “Star of David” and the “Seal of Solomon” by suggesting that the hexagram of the former is made up of overlapping triangles while the hexagram of the latter is intertwined:

This argument seems to be without any foundation; the two symbols are one and the same, with the Star of David often depicted intertwined and the Seal of Solomon depicted overlapping (sometimes within a circle).

A Symbol for Israel

Hexagram on ‘Seder Tefillot’, the first siddur printed in Central Europe. (From Scholem’s ‘Kabbalah’, pg. 365)

Gershom Scholem argues that Jews in the 18th and 19th centuries were looking for a unifying symbol to represent themselves, something like the cross of the Christians or the crescent moon of the Muslims. In the city of Prague, the hexagram had been associated with Jews since the 14th century. It was back in 1354 that King Charles IV of Bohemia granted the Jewish community its own flag, with the hexagram upon a red banner. It soon started to appear on the synagogues of Prague. In 1512, the first modern siddur was printed in Prague and, not surprisingly, had the hexagram on its cover. After the Jews’ vital assistance to the city’s defences in 1648, the community was granted another royal flag, now with a yellow star on a red banner. This flag has been used by the community ever since.

The timing couldn’t be better (or worse). Just a few years later, the Shabbatean heresy would begin, and Prague was soon one of the movement’s strongholds. It appears that the Shabbateans adopted the symbol and used it in secret to identify each other. Scholem points out that use of the star was one of the reasons Rabbi Yakov Emden accused Rabbi Yonatan Eybeschutz of being a closet Shabbatean.

Star from 5th century CE Byzantine Church uncovered at Khirbet Sufa in the Negev

Interestingly, among the Shabbateans the symbol was known as Magen ben David, the Shield of the Son of David, ie. the Shield of the Messiah. This makes sense considering they believed that Shabbatai Tzvi was Mashiach. This isn’t too different from that star-bearing Capernaum synagogue where Jesus supposedly preached. Not too far away from Capernaum in Israel, a 5th century Byzantine church was uncovered, also with the hexagram symbol. Another ancient church in Tiberias displays the star. Perhaps early Christians believed the hexagram was a symbol of their purported Ben David, too! Indeed, to this day one of the Pope’s mitres (the ceremonial hat) has the hexagram prominently displayed upon it.

Scholem suggests that the symbol is referred to as Magen ben David in older Kabbalistic texts that predate the Shabbateans (which is where they would have gotten it). Since Kabbalistic teachings date back to at least the Second Temple period, it is possible that even in the time of Jesus there was a tradition of the hexagram being a messianic symbol. In truth, calling it the Shield of David is problematic, since the accepted tradition is that David’s shield had the Menorah upon it. It was Solomon that apparently used the hexagram to shield from demons. And Solomon is literally a ben David, the son of King David, the very first potential Mashiach ben David in history.

Mashiach’s role is to reunite all of the Jews in Israel, and to restore the original Twelve Tribes. The twelve vertices of the hexagram are said to refer to the Twelve Tribes of Israel, all reunited as one. Meanwhile, the land of Israel itself is often described in sevens: the seven Canaanite nations, and the seven shepherds to whom it was promised; the “seven species” through which the land is praised, and the seventy names that the land is known by (see Midrash HaGadol on Genesis 46:8). It is therefore most appropriate that the Zionist movement which sought to restore the Jews to their ancestral land chose the hexagram as its symbol.

While the secular Theodor Herzl drew up a flag that had seven golden stars on a white banner, it was the Orthodox-born and raised David Wolffsohn that came up with the modern flag of Israel, basing the design on the tallit. Wolffsohn responded to Herzl’s call to create a flag for the Jews by stating: “We have a flag—and it is blue and white. The tallit with which we wrap ourselves when we pray: that is our symbol. Let us take this tallit from its bag and unroll it before the eyes of Israel and the eyes of all nations.”

By this point in history, the Star of David was used by Jewish communities and synagogues across Europe and beyond, so it was natural for it to be emblazoned upon the blue and white tallit-flag. Around the same time, the Orthodox Jewish scholar Franz Rosenzweig (1886-1929) wrote The Star of Redemption, where he used the hexagram to explain the relationship between God and man. Previously, Rosenzweig had resolved to convert to Christianity, then decided to spend one more day as a Jew on Yom Kippur. That day, in a small Orthodox shul in Berlin, Rosenzweig experienced a mystical revelation and an awakening. He became a pious baal teshuva, and a passionate champion for traditional Judaism. His popular “star of redemption” added further meaning to Israel’s new flag.

Rosenzweig’s ‘Star of Redemption’

There is one last irony in all of this: the same hexagram was used by the Nazis to degrade the Jews in their attempt to eradicate the nation (likely based on the use of a yellow badge forced upon Jews in some medieval-era towns centuries earlier). To proudly fly the Star of David today is to demonstrate that we are still here, stronger than ever, and we are not going anywhere. We took those stars off of our beaten and bloodied robes and put them on our tanks and jets. And now we await Mashiach ben David, Magen ben David, to come and take command of them. It is, after all, his symbol.
