The Word the Torah Left Open

The Torah told Noah to place a tzohar in the ark. The word appears only once in the entire Hebrew Bible. It can mean a window. It can mean a noon light. It can mean something else entirely, something the text does not fully define, which is exactly what the rabbis heard when they read it. A word with a surplus of possible meaning sitting inside the building instructions for the only vessel that would survive the end of the world. They would not let it stay flat.

Rabbi Abba bar Kahana said window. Rabbi Levi said precious stone. Rabbi Pinchas, quoting Rabbi Levi, made the claim specific and arresting: for the entire year Noah was in the ark, he had no need of the sun or moon. This stone provided light. When it dimmed, Noah knew it was day. When it shone bright, it was night.

The Stone From the River Pishon

Targum Pseudo-Jonathan on the verse goes further. God's instruction to Noah was not simply to make a light for the ark. It was to travel to the Pishon river and bring a specific stone from there. The Pishon is one of the four rivers that flowed from Eden. It runs through the land of Havilah, where, as Genesis notes, there is gold and bdellium and onyx stone. Noah was told to go to the edge of paradise and retrieve a gem from that territory and install it inside the vessel.

The tzohar was, in this reading, not a window at all. It was a piece of Eden, carried from the gates of the garden that had been closed since the expulsion, brought aboard a wooden ship to survive the destruction of everything else. The light that would fill Noah's year in the Flood was the same quality of light that had once filled the world before the primordial light was hidden.

Adam's Stone, Passed Forward

The Talmud in Sanhedrin connects the tzohar to an earlier history. After Adam was expelled from Eden, the angel Raziel brought him a glowing stone. It contained a spark of the primordial light, the or haganuz, the light God had created on the first day and then hidden away when the world fell short of justifying it. Adam kept this stone. He passed it forward. Eventually it reached Noah, who placed it in the ark.

This makes the tzohar not only a practical solution to the darkness inside a sealed vessel. It is a chain of transmission from creation's first light through the man expelled from Eden to the man who survived the Flood. The light that guided Noah through a year of water and darkness was light that had been present at the beginning of everything. It had been compressed into stone and passed from generation to generation until it was needed most.

Light for Holy Logistics

The rabbis do not elevate the tzohar above its practical function. Noah had to feed every living creature that boarded the ark, every animal in every category, at the correct times, continuously, for a year. He had to clean stalls, manage water, keep order, care for his family, and count the days until the waters receded. The midrash does not pretend this was effortless. Rabbi Huna preserves a tradition of hiding from enemy soldiers in a cave in Tiberias, using a lamp made of similar material to find his way in underground darkness. The tzohar is that kind of light, practical first. The stone served holy logistics.

That practicality is part of the wonder. God did not give Noah a ship full of symbolic lighting. God gave him something that worked. The same stone that contained Eden's light could also light an animal stall at feeding time. The sacred and the functional were not separated. The light from the beginning of the world was bright enough to count feed portions by.

Onyx From the Pishon to the Breastplate

The Pishon river's stones had more than one destination. Targum Pseudo-Jonathan on Exodus reports that when the high priest needed onyx stones for the ephod and the breastplate, the clouds of heaven went to the Pishon and drew up the stones from the Edenic river bed. The same source as Noah's tzohar. The breastplate that Aaron wore, the one that carried the names of the twelve tribes, was made partly from stones gathered by divine couriers from the edge of paradise.

Eden persisted as a material source even after its gates were closed. Its stones could be retrieved. Its gem deposits remained available to the right mission, carried by the right agents, for the right holy purpose.

Sanhedrin 108bTalmud Bavli, Sanhedrin

"A light you shall make for the ark" (Genesis 6:16). Rabbi Yochanan said: The Holy One, blessed be He, said to Noah: Set in it precious stones and pearls, so that they may give light to you like the noonday.

Targum Pseudo-Jonathan on Genesis 6:16Targum Pseudo-Jonathan on Genesis

The Torah says to set a "tzohar" in the ark, a mysterious word usually translated "window" or "light." Targum Pseudo-Jonathan on (Genesis 6:16) tells us Noah had to fetch it.

"Go thou unto Phison, and take from thence a precious stone, and fix it in the ark to illuminate you."

Pishon is one of the four rivers that flowed out of Eden (Genesis 2:11). Noah is instructed to travel to the edge of paradise, retrieve a luminous gem, and install it inside the ark. The ark's light source is literally a piece of Eden.

The light that would survive the Flood

The Targumist's image is haunting. The sun will be blotted out for forty days and nights. Rain, darkness, the waters above and below reunited. In that total blackness, the only light in the only surviving vessel comes from a stone taken from the gates of paradise.

Jewish mystical tradition develops this further. The stone is sometimes identified with the shamir or with the glowing gems that will later light Solomon's Temple. In the Targumist's hand, the point is simpler: even during the destruction of the world, a splinter of Eden's light is preserved in the ark. And where the light is preserved, humanity can be preserved.

"With the measure of a cubit shalt thou complete it above. And a door shalt thou set in the side of the ark; and with dwelling-places, inferior, second, and third, shalt thou make it." Three stories, one for humans, one for animals, one for waste, by late antique tradition. A precise, livable ark under a single glowing stone.

Bereshit Rabbah 31:11Bereshit Rabbah

What about the nitty-gritty? How did Noah see in there? Where did everyone go to the bathroom?

Our Sages, wrestling with the very same questions, dove deep into the Torah's description of the Ark, and what they found is truly fascinating..".

That "bright item," or tzohar, is where the debate begins. Rabbi Abba bar Kahana thought it was a window. Simple enough. But Rabbi Levi had a different idea. He envisioned it as a luminous, precious stone. And Rabbi Pinḥas, quoting Rabbi Levi, paints a stunning picture: for the entire year Noah was in the ark, he didn't need the sun or moon. Instead, this precious stone provided light. When it dimmed, Noah knew it was day; when it shone brightly, it was night.

Rabbi Huna even shares a story of hiding from enemy troops in a cave in Tiberias, using lamps to distinguish between day and night, echoing the idea of an artificial light source determining time.

So, a window or a gemstone? What do you think?

Then there's the question of the ark's internal structure. The verse continues, "..and to a cubit you shall complete it at the top." This refers to the dimensions of the ark. Rabbi Yehuda and Rabbi Neḥemya disagree on the layout. Rabbi Yehuda describes 360 compartments, each ten by ten cubits, arranged in rows. Rabbi Neḥemya imagines 900 smaller compartments, each six by six cubits, with aisles in between.

These aren't just dry measurements; they're attempts to understand how Noah could possibly manage all those animals! How did he organize them? How did he feed them? These Rabbis are trying to make sense of the practical realities of this miraculous story.

And what about the shape? Did the ark narrow at the top? Rabbi Yehuda and Rabbi Neḥemya disagree again, with Rabbi Neḥemya suggesting it was more like a vault, continuously inclining as it ascended to its single cubit peak. These details matter because they affect how the space inside the ark was used.

The Torah also states, "And the entrance of the ark you shall place at its side." Rabbi Yitzḥak sees practical wisdom in this, advising that in any large room, the door should be placed to the side to maximize usable space. It's a small detail, but it shows how the Rabbis found everyday relevance in the Torah's narratives.

Finally, the text describes the ark's three levels: "Lower, second-level, and third stories you shall craft it." But what was on each level? Some say the bottom level was for refuse, the middle for Noah, his family, and the pure animals, and the top for the impure animals. Others swap the bottom and top levels. Either way, the question of waste disposal arises! The Rabbis suggest a partitioned opening on the top level, allowing Noah to sweep the refuse aside without it falling to the levels below.

And here's a beautiful, almost mystical idea: "You shall craft it [taaseha]" is interpreted as "it shall become made [te'aseh]." The ark, the Midrash (rabbinic interpretive commentary) suggests, assisted in its own construction. The task was too great for human hands alone, so a miraculous element was involved.

Isn't that incredible? The ark itself, almost a living entity, helping to bring about its own creation.

So, what do we take away from all this? It's more than just architectural plans for a giant boat. It's about the human need to understand the divine, to confront the logistics of miracles, and to find meaning in every detail of the sacred text. It reminds us that even in the most fantastical stories, there are practical questions, human struggles, and ultimately, a profound sense of wonder. And maybe, just maybe, a hint of magic in the very act of creation itself.

Bereshit Rabbah 16:2Bereshit Rabbah

A reader can just gloss over those descriptions of the Garden of Eden, but the Rabbis of the Midrash (rabbinic interpretive commentary), those ancient interpreters of the Torah, saw so much more. to just a tiny piece, from Bereshit Rabbah 16, and see what treasures we can unearth.

Okay, a river named Pishon. So what? Well, the Midrash asks, why Pishon? They connect it to the Hebrew word for flax, pishtan, suggesting the river was known for helping flax grow. It also mentions the water flows smoothly, shofi, and points out that "shofi" contains the first three letters of Pishon, just rearranged a bit. Clever. These Rabbis were masters of wordplay, finding hidden connections everywhere.

The verse says the Pishon encircles the "entire land of Ḥavila." But, the Midrash points out, Ḥavila didn't even exist yet! Ḥavila, as in, the person, was a great-grandson of Noah (Genesis 10:7). So how can the river encircle a land named after someone who hadn’t been born yet?

The answer they give is beautiful: "He tells the outcome from the outset" (Isaiah 46:10). This is about God's all-knowing nature. God knows the future. God knew Ḥavila would exist, so the land could be named in advance. It's a reminder of divine foresight woven right into the creation story.

Then there's the gold. "Where the gold is," the verse continues. And not just any gold, but “the gold,” implying pure, high-quality gold. The very next verse continues, "And the gold of that land is good; there is bdellium there, and onyx stone" (Genesis 2:12). The repetition of "gold" sparks even more commentary.

Rabbi Yitzḥak says gold is good to have at home, good to take on the road. It's a valuable resource in any situation. Rabbi Abahu adds that God did the world a favor by creating gold, because it allows people to make change and use it for many things. Reish Lakish, however, takes a different view. He says the world wasn't worthy of gold for everyday use! He believed it was created specifically for the Temple, linking it to the verse, "And the gold of that land is good," comparing it to "This good mountain and Lebanon" (Deuteronomy 3:25), a phrase that refers to the Temple itself. So, gold's ultimate purpose, according to this interpretation, is for sacred service.

Finally, what about this bdellium, or bedolaḥ in Hebrew? What is it? Rabbi Aivu asks if it's the same bedolaḥ that spice-mixers use. He dismisses the idea. He refers to (Numbers 11:7), where bedolaḥ is described as a precious stone. "Just as that is a gem," he says, "so, too, this is a gem." So, in the Garden of Eden, we're talking about something precious, not just a common spice.

What does this all mean? Maybe it's a reminder that even the simplest verses can hold layers of meaning, waiting to be uncovered. The Rabbis of the Midrash saw the Torah not as a static text, but as a living document, constantly revealing new insights. And maybe, just maybe, it's an invitation for us to do the same. To look beyond the surface, to ask questions, and to discover the hidden treasures within our own traditions.

Targum Pseudo-Jonathan on Exodus 35:27Targum Pseudo-Jonathan on Exodus

Where did the onyx stones for the high priest's ephod come from? The Torah does not say. But Targum Pseudo-Jonathan on (Exodus 35:27) tells one of the strangest mineral-supply stories in rabbinic literature: the clouds of heaven went to the Pishon, and drew up from thence onyx stones, and stones for infilling, to enchase the ephod and the breastplate.

The Pishon is one of the four rivers that flowed out of Eden (Genesis 2:11-12). The Torah explicitly notes that the Pishon winds through the land of Havilah, where there is gold… bdellium and the onyx stone. The Targum reaches back to that verse and makes the miracle explicit. The onyx of the breastplate is not ordinary onyx. It is Edenic onyx, fetched by clouds that acted as God's couriers.

The stones for "infilling" were the twelve gems of the breastplate, one for each tribe of Israel, engraved with the tribe's name, worn over the high priest's heart when he entered the Holy of Holies. The Targum insists these were pulled from the river of paradise itself.

Then a second detail: the clouds spread them upon the face of the wilderness, and the princes of Israel went, and brought them for the need of the work. The stones arrived in the desert by supernatural delivery, but Israelite hands still had to gather them. Miracles in Jewish thought rarely bypass human action; they only pave the way for it.

The takeaway: the Tabernacle was stitched from two sources, what Israel brought out of Egypt, and what the clouds of heaven fetched from Eden. The dwelling of God required materials from both ends of the human story, the fallen world and the paradise behind it.

Yalkut Shimoni on Torah 57:1Yalkut Shimoni on Torah

"And the LORD shut him in" (Genesis 7:16). The Holy One, blessed be He, shut up the sun and the moon, and they did not give light all twelve months, as it is said, "Who commands the sun [cheres] and it does not shine." And how did Noah see to function? The Holy One, blessed be He, prepared for him a precious stone, and he made use of its light. When the wicked saw that they were lost, they sought to overturn the ark; He surrounded the ark with lions, and they devoured them, as it is said, "And the LORD shut him in," just as it says, "My God sent His angel and shut the mouths of the lions, and they did not harm me" (Daniel 6:23). "Fifteen cubits upward did the waters prevail," and so forth (Genesis 7:19-20). And which measure is greater, the measure of good or the measure of punishment? You must say the measure of good is greater. Regarding the measure of punishment He says, "And the windows of heaven were opened"; regarding the measure of good He says, "And He commanded the skies above and opened the doors of heaven, and rained down manna upon them to eat, and gave them the grain of heaven" (Psalms 78:23-24). How many windows are in a door? Four and four, hence eight. It is found that the manna that fell for Israel was sixty cubits high. Are they comparable? There it was over forty days, here in a single hour; there for the whole world, here for Israel alone. Rather, Rabbi Elazar of Modi'in derives it by a verbal analogy of "opening" with "opening." Issi ben Yehuda says: The manna that came down for Israel kept rising up higher until all the kings of east and west could see it, as it is said, "You prepare before me a table in the presence of my enemies; You anoint my head with oil, my cup overflows" (Psalms 23:5). Abaye said: Learn from this that the cup of David in the world to come holds two hundred and twenty-one log, as it is said, "my cup overflows [revayah]"; revayah in gematria equals this.
