Solomon's Stone: The Ancient Mining Valley That Keeps Confirming the Bible

Ancient copper mining in Timna Valley during the era of King Solomon — workers resting, carrying ore and tending smelting furnaces in the red sandstone desert landscape

September 29, 2026

There is a place in the southern tip of Israel, about nineteen miles north of the Red Sea, where the desert opens into a broad, sandstone valley of extraordinary beauty. Towering rock formations rise from the valley floor in dramatic columns of red and ochre, carved by millennia of wind and erosion into shapes that look almost architectural. Ancient miners gave these formations their name: Solomon's Pillars.

The name was once considered little more than romantic legend. For decades, the scholarly consensus held that the copper mines of Timna Valley had been Egyptian operations, active in the Bronze Age around the 13th and 14th century BCE, with no meaningful connection to the biblical Kings David and Solomon. The Pillars, the theory went, were simply named after Solomon by over-enthusiastic 19th-century explorers looking to connect the landscape to scripture.

That consensus has now been overturned entirely. And the evidence that overturned it came, among other things, from donkey dung.

The Valley the Bible Remembered

Scripture places this region squarely within the story of Israel's united monarchy. The Bible records that David subjugated the area now known as Timna, placing garrisons throughout the land so that the Edomites became his subjects.

"David also defeated the Edomites. He put garrisons in Edom, and all the Edomites became David's servants." - 2 Samuel 8:14 (ESV)

His son Solomon, according to scripture, used vast quantities of copper in the building of the Temple in Jerusalem, and established the Red Sea port of Ezion-geber — the ancient name of Eilat — at the southern end of the Arava Valley.

"King Solomon also built a fleet of ships at Ezion-geber, which is near Eloth on the shore of the Red Sea, in the land of Edom." - 1 Kings 9:26 (ESV)

The copper to build the Temple had to come from somewhere. Timna, nineteen miles to the north, was among the most productive copper-producing sites in the ancient Near Eastern world. But for much of the 20th century, archaeologists disputed the connection. The Egyptian temple to Hathor at the foot of Solomon's Pillars, excavated by Israeli archaeologist Beno Rothenberg beginning in the 1960s, was definitively dated to the Egyptian New Kingdom period, 14th to 12th century BCE. By the time of David and Solomon, the Egyptians had withdrawn, and the prevailing view was that the mines had gone with them.

The Bible, many scholars argued, was simply wrong about this. Or at best, elaborating.

Slaves' Hill and the Evidence That Changed Everything

Beginning in 2009, Dr. Erez Ben-Yosef of Tel Aviv University's Jacob M. Alkow Department of Archaeology and Near Eastern Cultures began a series of excavations at previously unexplored sites in the Timna Valley. What he and his team found at a sandstone mesa called Slaves' Hill would fundamentally rewrite the story of who worked this desert, and when.

Slaves' Hill — named by the archaeologist Nelson Glueck, who first surveyed the site in 1934 — is a dramatic flat-topped formation surrounded by steep cliffs. At its summit, Ben-Yosef's team uncovered the remains of one of the largest ancient copper smelting camps in the entire Timna Valley: hundreds of furnaces, deep layers of copper slag, fragments of rope, fabrics, and food remains, and the ruins of a fortified gatehouse complex with what appeared to be donkey stables.

The question was when. The answer came from radiocarbon dating of the organic materials uncovered at the site. Eleven olive and date pits found in the excavation were sent to Oxford University for high-precision analysis. The results were unambiguous. The materials dated to the 10th century BCE — precisely the era of the biblical Kings David and Solomon.

Then came the donkey dung.

Deep in the arid desert, preserved for three thousand years by the extraordinarily dry climate of the Arava, Ben-Yosef's team uncovered what appeared to be relatively recent animal manure near the ancient stables. Initial analysis suggested it was too intact to be ancient. Radiocarbon dating told a different story. The dung was three thousand years old — from the 10th century BCE. "It was hard to believe," Ben-Yosef remarked.

The implications were considerable. The dung samples contained seeds and pollen so intact that researchers could determine the animals' diet, which turned out to include feed imported from more than 100 miles to the north, near the Mediterranean coast. This was not a primitive desert outpost. This was a complex, highly organised operation with long-distance trade connections and the logistical infrastructure to sustain them in the middle of a hostile desert.

"In Timna Valley, we unearthed a society with undoubtedly significant development, organization, and power." — Dr. Erez Ben-Yosef, Tel Aviv University

A Sophisticated People in the Desert

One of the most striking aspects of the Timna findings has been what they reveal about the daily lives of the people who worked the mines. Because the desert's extreme dryness preserves organic materials that normally disintegrate in more temperate climates, archaeologists at Timna have been able to recover items that would be invisible anywhere else.

The dyed textiles recovered from the smelting camps at Slaves' Hill tell an unexpected story. Analysis published in the journal PLOS ONE identified the presence of two sophisticated organic dyes — rubia tinctorum and indigotin — among the earliest examples of industrial chemical dyeing from the ancient Levant. These were not rough work clothes. They were high quality dyed fabrics, the kind associated with an elite, obtained through long-distance trade.

"This suggests the existence of an elite that was interested in these high quality textiles and invested efforts in procuring them by long-distance trade." — PLOS ONE, Central Timna Valley Project

The fortified gatehouse complex discovered at Slaves' Hill adds another layer to this picture. It points, Ben-Yosef has argued, to a community organised enough to build and maintain military fortifications in one of the most inhospitable environments in the ancient world. The Bible records that David marched his armies deep into the desert to engage the Edomites at precisely this location and period. The fortified walls Ben-Yosef found are consistent with a site that was very likely a military target.

The Temple of Hathor and Its Unexpected Sequel

At the foot of Solomon's Pillars, the Egyptian Hathor temple excavated by Rothenberg remains one of the most evocative sites in the valley. Founded during the reign of Pharaoh Seti I around 1318 BCE and rebuilt under Ramses II, it served the Egyptian mining expeditions and their local collaborators for nearly two centuries. Thousands of cultic artifacts were recovered from its ruins, including depictions of the cow-eared goddess and a bronze serpent that some scholars have connected to the biblical account of Moses and the bronze snake in the wilderness.

"And the LORD said to Moses, 'Make a fiery serpent and set it on a pole, and everyone who is bitten, when he sees it, shall live.'" - Numbers 21:8 (ESV)

When the Egyptians finally withdrew from Timna — around the 12th century BCE — they left behind a temple, a tradition of copper production, and a landscape rich with a remarkable by-product that would eventually carry the name of the greatest king in Israel's history.

The Stone Beneath Solomon's Mines

The copper ore of Timna Valley is embedded in red sandstone. When copper sulphides are deposited in porous sandstone and then subjected to continued hydrothermal activity and oxidation over millions of years, they produce a unique mineral formation — a fusion of chrysocolla, malachite, azurite, and turquoise that swirls together in vivid patterns of blue, green, and teal that look different in every single specimen.

This stone has been mined at Timna Valley since approximately 4600 BCE, making it one of the earliest systematically mined mineral deposits in the world. It carries the name of Israel's southernmost city, Eilat — the ancient Ezion-geber of Solomon's Red Sea port. But it is also called, and has long been called, by another name: King Solomon Stone.

Archaeological evidence confirms that the Timna Valley mines were actively exploited during the 10th century BCE — the biblical era of King Solomon — and according to historical tradition, the vast wealth of Solomon's kingdom was heavily supported by his control over these copper reserves. The vibrant stones were a natural by-product of the extensive copper mining operations that made this valley one of the most productive industrial sites in the ancient world.

The stone itself is not mentioned by name in scripture. But the copper-rich landscape that produced it is woven through the biblical narrative at every turn, from the bronze furnishings of the Tabernacle in the wilderness, through David's conquest of Edom, to Solomon's Temple and his Red Sea trade routes. Every piece of King Solomon Stone carries within it the geological fingerprint of this specific valley, this specific sandstone, this specific thousand-year chapter in the history of God's people in the land He gave them.

Why This Matters

The ongoing excavations at Timna matter for the same reason that all biblical archaeology matters: not because our faith depends on physical proof, but because the Gospel accounts, and the historical books of scripture, were never written as abstract mythology. They describe real places, real people, real conflicts fought over real terrain. And Timna is real terrain, with real furnaces, real dung, real textiles, and real olive pits that Oxford University dated to the exact century scripture describes.

As Professor Ben-Yosef himself has stated clearly: "Today we know that copper production actually peaked here at about the time of Kings David and Solomon. The Bible never mentions the mines as such, but it does tell us that David conquered the area of Timna, placing garrisons throughout the land, and that his son Solomon used huge quantities of copper for building the Temple in Jerusalem."

The so-called biblical minimalists who argued for decades that David and Solomon were fictional characters, or at most minor chieftains ruling a hill-country village, have found it increasingly difficult to sustain that position against the accumulating weight of archaeological evidence. The copper mines of Timna, dated with precision to the era of the united monarchy, reveal a sophisticated, trade-connected, militarily organised society operating exactly where and when the Bible says it was.

For believers, these findings are not the foundation of faith. They are, rather, a quiet and remarkable confirmation of something faith already knew: that the God of scripture is the God of history, and that the history He moved through left marks that three thousand years of desert and time have not managed to erase.

"The grass withers and the flower fades, but the word of our God will stand forever." - Isaiah 40:8 (ESV)

The mines at Timna are silent now, protected within a national park. The furnaces are cold. The donkeys are long gone. But the stone they left behind — blue and green and swirling with the minerals of an ancient landscape — still carries the name of the king who once commanded this valley.

And we are honoured, at Moriah Cross Works, to set a piece of it into the hands of the next generation.
