Brass; Brazen
Bronze in the Biblical World
When older English translations of the Bible use the word "brass," they almost always mean bronze, which is an alloy of copper and tin. True brass, made from copper and zinc, was not widely produced until much later in history. Bronze was the defining metal of an entire age of human civilization, and the transition from the Bronze Age to the Iron Age occurred during the period of the Israelite conquest of Canaan.
Moses described the Promised Land as one "where the rocks are iron and you can dig copper out of the hills" (Deuteronomy 8:9), pointing to the natural mineral resources that would sustain Israelite metalworking. The Canaanites were already skilled in bronze production when Israel arrived, and the Israelites inherited and developed this technology.
Bronze in the Tabernacle and Temple
Bronze played a central role in Israel's sacred architecture. The altar of burnt offering in the tabernacle was overlaid with bronze (Exodus 27:1-2), and many of its utensils, including pots, shovels, basins, and forks, were made of bronze (Exodus 27:3). The laver where the priests washed before entering the tabernacle was made of bronze, fashioned from the mirrors contributed by the women who served at the entrance (Exodus 38:8).
Solomon's temple featured even more elaborate bronze work. The master craftsman Huram (or Hiram) from Tyre cast two massive bronze pillars for the temple entrance, named Jakin and Boaz (1 Kings 7:15-22). He also made the "Sea of cast metal," a great bronze basin supported by twelve bronze oxen, which held approximately 11,500 gallons of water for ceremonial washing (1 Kings 7:23-26). Additionally, ten bronze movable stands supported ten bronze basins used for rinsing sacrificial offerings (1 Kings 7:27-39). The sheer quantity of bronze used in Solomon's temple was so great that it could not be weighed (1 Kings 7:47).
Bronze in Warfare and Daily Life
Bronze was the primary material for weapons and armor before iron became widely available. Goliath's armor included a bronze helmet, bronze coat of mail weighing five thousand shekels, and bronze leg armor, and his javelin had a bronze point (1 Samuel 17:5-7). Bronze was also used for shields, as when Pharaoh Shishak plundered the golden shields Solomon had made and Rehoboam replaced them with bronze ones (1 Kings 14:27).
In daily life, bronze was used for mirrors, cooking vessels, lamps, locks, nails, and cutting instruments. Archaeological excavations throughout Palestine have uncovered abundant bronze objects from the biblical period, confirming the widespread use of this versatile metal.
Bronze as a Symbol of Strength
Scripture frequently uses bronze figuratively to represent strength, firmness, and durability. God promised to break down "gates of bronze" (Psalm 107:16; Isaiah 45:2), meaning no fortress or obstacle could withstand his power. Micah prophesied that God would give Israel "horns of iron" and "hooves of bronze" to crush her enemies (Micah 4:13). When God called Jeremiah to prophetic ministry, he declared, "Today I have made you a fortified city, an iron pillar and a bronze wall" (Jeremiah 1:18; 15:20), indicating that the prophet would be able to withstand all opposition.
In Nebuchadnezzar's dream in Daniel 2, the belly and thighs of the great statue were made of bronze, representing the third world empire (Daniel 2:32, 39). The use of bronze to symbolize this kingdom conveyed both its strength and its place in the descending order of metals from gold through silver, bronze, and iron.
Bronze as a Symbol of Hardness and Obstinacy
Bronze also carries negative connotations in Scripture, particularly when describing human stubbornness against God. Isaiah declared to rebellious Israel, "Your neck is an iron sinew and your forehead is bronze" (Isaiah 48:4), meaning the people were inflexible and unyielding before God's word. Jeremiah described the wicked as "bronze and iron" (Jeremiah 6:28), emphasizing their hardened resistance to divine correction. Ezekiel declared that the people of Israel had become "dross" in a furnace, the worthless residue left behind when bronze and other base metals are refined (Ezekiel 22:18).
The Bronze Serpent and Its Significance
One of the most theologically significant bronze objects in Scripture is the bronze serpent made by Moses. When the Israelites were bitten by venomous snakes in the wilderness as judgment for their complaining, God instructed Moses to make a bronze snake and set it on a pole. Anyone who was bitten could look at the bronze serpent and live (Numbers 21:8-9). Jesus later pointed to this event as a foreshadowing of his own crucifixion: "Just as Moses lifted up the snake in the wilderness, so the Son of Man must be lifted up, that everyone who believes may have eternal life in him" (John 3:14-15).
The bronze serpent was eventually destroyed by King Hezekiah because the people had begun burning incense to it as an idol, calling it Nehushtan (2 Kings 18:4). This episode illustrates how even a divinely appointed object could become a snare when it was venerated in place of God.
Biblical Context
Bronze (brass) appears throughout the Bible in connection with the tabernacle furnishings (Exodus 27; 38), Solomon's temple (1 Kings 7), weapons and armor (1 Samuel 17:5-7), and the bronze serpent (Numbers 21:8-9). Figuratively, it represents strength (Jeremiah 1:18; Micah 4:13), world empires (Daniel 2:32, 39), and human stubbornness (Isaiah 48:4; Jeremiah 6:28). The bronze serpent is interpreted christologically in John 3:14-15.
Theological Significance
Bronze in Scripture reveals the intersection of the material and the sacred. God chose ordinary metals for his most holy objects, demonstrating that he works through created things to accomplish his purposes. The bronze serpent provides one of the Old Testament's clearest foreshadowings of Christ's atoning work on the cross. The negative symbolism of bronze as stubbornness warns against hardening oneself against God's word, while the positive symbolism of strength assures believers that God can make them firm and unshakable in their calling.
Historical Background
The transition from the Bronze Age to the Iron Age in Palestine occurred around 1200-1000 BC, roughly corresponding to the period of the Judges and the early monarchy. Copper was mined in the Arabah region (southern Israel/Jordan), Sinai, and Cyprus. Tin, the other component of bronze, was imported from distant sources, possibly Anatolia, the Balkans, or even Cornwall in Britain. Archaeological sites like Khirbet en-Nahas in Jordan have revealed massive copper smelting operations dating to the Iron Age. Bronze objects recovered from excavations include weapons, tools, vessels, figurines, and architectural fittings, confirming the central role of this metal in biblical-era life.
