The Bible contains many references to minerals and metals. Minerals can encompass a wide array of topics, thus the focus here is on valuable minerals such as ornamental stones as well as precious and useful metals.

Copper. References to copper within the Bible are few. Several passages discuss the basic origins of copper, such as the gathering of ore or the smelting process (Deut. 8:9; Job 28:2; Ezek. 22:18, 20; 24:11). Several NT passages acknowledge the presence of minted copper coins as currency (Matt. 10:9; Mark 12:42; Luke 21:2). Pure copper, however, was hard to use, although it could be combined with tin to make the alloy bronze.

Bronze. The first biblical reference to bronze is found in Gen. 4:22, in which we are told that Tubal-Cain forged tools out of bronze and iron. Next, bronze is mentioned in its use in the tabernacle built in the desert. Among the bronze items included were the many bronze clasps and bases for the tent construction (Exod. 26:11, 37; 27:10 11, 17–19). The altar and all its utensils were made of, or overlaid with, bronze (27:1–8). God also instructed Moses to make a bronze basin for washing (30:18). Moses also made a snake out of bronze and placed it on top of his staff when the Israelites were struck with an abundance of venomous snakes (Num. 21:9). Samson was bound with shackles of bronze (Judg. 16:21), and Goliath wore armor and carried weapons of bronze (1 Sam. 17:5–6). Solomon used an extensive amount of bronze in his building of the temple (2 Kings 25:16), and there was bronze in the statue that Daniel dreamed of (Dan. 2:32, 35). Many of the prophets used bronze as a way to discuss something that was to be strong or strengthened by God (Isa. 45:2; Jer. 1:18; Ezek. 40:3).

Iron and steel. One of the earliest references to iron in Scripture is its use by the Canaanites to make chariots (Josh. 17:16, 18). This would have been an early use of the metal in the Iron Age I period (1200–1000 BC). Also, Goliath’s spear, which was as big as a weaver’s rod, is said to have had a head made of iron (1 Sam. 17:7). Elisha’s miracle of making a borrowed ax head float (2 Kings 6:6) shows the continued value of the metal. In his latter days, David amassed iron among the goods to give Solomon to use in building the temple (1 Chron. 22:14; 29:2); Solomon later used these materials with the help of Huram-Abi (2 Chron. 2:13–14). Ezekiel discusses the economic value of iron in the context of trading (Ezek. 27:12, 19), and Daniel uses it as a metaphor for discussing strength (Dan. 2:40–41). The NT recognizes the strength of iron when discussing Christ’s iron scepter (Rev. 2:27; 19:15).

Tin. Tin was initially used mainly to produce the copper alloy bronze. Tin was not used in its pure form until well into the Roman period, and even then seldom by itself. The sources of tin in the ancient world are currently debated. The tin from large deposits in Tarshish in southern Spain (Ezek. 27:12) was available through Phoenician traders. Tin is also found in large deposits in Anatolia, but it is currently unknown whether these deposits had been discovered and used during biblical times. A third option is modern-day Afghanistan. Archaeologists have discovered in modern Turkey the remains of a wrecked ship, dated to around 1350 BC, that was carrying ten tons of copper ingots and about one ton of tin ingots. These ingots possibly originated in the area of modern-day Afghanistan and were bound for the Mediterranean trade routes. Tin is mentioned only four times in Scripture, always within a list of other metals (Num. 31:22; Ezek. 22:18, 20; 27:12).

Lead. Lead was used early in human history, but its applications were few. It would have been mined with copper and silver ore and then extracted as a by-product. The Romans used it for various implements, most notably wine vessels. It is referenced nine times within Scripture, either in a list or in reference to its weight. The only two times it is referenced as an object is when Job mentions a lead writing implement (Job 19:24), and when Zechariah has the vision of a woman sitting in the basket with a lead cover (Zech. 5:7, 8).

Gold and silver. Sought after for much of human history, gold and silver have been worked by humans for their ornamental value. The practical uses of these metals within the biblical setting were constrained mainly to their economic and ornamental value. Gold and silver jewelry were used as a form of payment and were minted into coins during the Greco-Roman era. Gold objects are relatively scarce in archaeological finds, mainly because most gold items would have been part of a large treasury carried off as tribute or plunder. Silver appears in the archaeological record more frequently; a remarkable hoard of silver in lump form was found at Eshtemoa (see 1 Sam. 30:26–28). This silver has been dated to the time of the kingdom of Judah, after the northern kingdom of Israel had fallen. The silver in raw lump form was most likely used as a monetary payment, even though it had not yet been minted into coins.

Gold in the ancient world came largely from Egypt and northern Africa. The Bible mentions Havilah as a land of gold (Gen. 2:11), as well as Ophir (1 Kings 9:28), but the exact location of both places is unknown. Silver was mined in southern Spain, along with other metals, and brought to the area through sea trading. The Athenians of the Classical period were also known for their vast silver-mining operations.

Silver and gold are mentioned repeatedly in the OT in reference to their uses in trading and their economic value. Most notably, the Israelites asked their Egyptian neighbors to give them gold and silver items just before they left Egypt (Exod. 3:22). The tabernacle was highly ornamented with these two metals, as was the temple built by Solomon. It is said that Solomon made the nation so wealthy that silver was considered as plentiful as stone (1 Kings 10:27). Perhaps the most notorious articles of silver within Scripture are those paid to Judas for his betrayal of Jesus (Matt. 26:15).

Precious stones. Stones of various origins were used in and around Palestine. The Bible makes few references to their use. Like gold and silver, they were used mainly for their ornamental value. Their scarcity made them highly prized. One notable exception is turquoise. The Egyptian pharaohs were fascinated with turquoise, and they mined extensively for it on the Sinai Peninsula. The remains of several turquoise mines have been found with Canaanite markings, indicating the presence of Canaanite slaves working the Egyptian mines. There was also a line of forts along the northern edge of the Egyptian Empire, used presumably to protect the pharaohs’ turquoise interests. Precious stones were also found in Syria, where Phoenician traders would have been able to bring them from other parts of the known world.

Exodus 28:17–21 describes twelve stones set in the breastpiece worn by the Israelite high priest. Twelve stones likewise appear in the foundations of the new Jerusalem (Rev. 21:19–20). Ezekiel uses nine of these same twelve stones to discuss the adornment of the king of Tyre (Ezek. 28:13).

The Bible uses the blanket term “precious stones” to denote a hoard of riches, such as that owned by Solomon (1 Kings 10:10).
