Why does the word…
steel appear in some Bibles?

The appearance of the English word “steel” is a translation artifact of older Bibles. The original Hebrew is talking about bronze (and, in one uncertain case, possibly hardened iron/steel). There is no anachronism in the source texts.

The word “steel” in the Bible is almost entirely a translation choice in older English versions (especially the King James Version), not a claim in the original Hebrew that modern steel existed before it was technologically possible.

What does the Hebrew actually say?

The main places “steel” appears in the KJV are:

He teacheth my hands to war; so that a bow of steel is broken by mine arms. —2 Samuel 22:35 and Psalm 18:34 KJV / Hebrew: kesheth-nehushah
He shall flee from the iron weapon, and the bow of steel shall strike him through. —Job 20:24 KJV
Shall iron break the northern iron and the steel? —Jeremiah 15:12 KJV

In these verses the Hebrew is nechushah / nechosheth (related forms of the ordinary word for copper/bronze). This is the same root used hundreds of times for bronze objects, vessels, and weapons. Modern translations (NIV, ESV, NASB, etc.) correctly render these as “bronze” or “bow of bronze.” Older revisions of the KJV tradition often changed “steel” to “brass” (which in early modern English frequently meant bronze, the copper-tin alloy actually used in the ancient Near East).

A rarer word, peladot (Strong’s 6393), appears once in Nahum 2:3. The KJV translates it as “flaming torches,” while some later versions render it “steel” (referring to metal fittings on chariots). Its meaning is uncertain; it may be related to later Persian/Arabic/Syriac words for high-quality iron or steel, but it is not a clear, unambiguous reference to steel.

Why did the KJV used “steel”?

In early 17th-century English, translators sometimes chose “steel” to emphasize hardness and strength. The underlying Hebrew simply referred to bronze (the hard metal of the time for many purposes). This is a classic case of a later English word being applied to an older material concept.

What is the history of relevant metallurgy on this topic?

Bronze (copper + tin) was the dominant hard metal through the Bronze Age and well into the early Iron Age
Ironworking began in the ancient Near East in the 2nd millennium BC; the broader Iron Age transition is usually dated around 1200–1000 BC.
Early steel (iron intentionally carburized—heated with carbon from charcoal to harden it) was produced in the Eastern Mediterranean and Near East by roughly 1000 BC, sometimes with quenching and tempering. Archaeological examples include a well-known 11th-century BC steel pick from Mount Adir in Upper Galilee and other carburized iron tools and weapons from Iron Age sites in the Levant.

The Bible frequently mentions both bronze and iron in ways that fit this technological timeline. It does not clearly distinguish “steel” as a separate category from iron, which is normal for the period. Claims that steel was completely unknown until centuries after the biblical era are outdated.

Was some steel produced in the regions around ancient Israel?

Early carburized iron (steel) was being produced in the Levant by around the 11th century BCE, as shown by finds such as the quenched-and-tempered steel pick from Mount Adir in Upper Galilee. The composition and redaction of most of the Hebrew Bible overlap with or postdate that period (roughly the early first millennium BCE into the Persian era). So the material itself was available in the right time and place.

Are there reasons steel was not directly mentioned in the Bible?

The main reasons it is not clearly and directly named are linguistic and practical:

No standard Hebrew term for steel separate from iron. The ordinary word for iron is barzel. Biblical Hebrew (like many ancient languages) does not appear to have had a common, dedicated technical word that cleanly distinguished “steel” (intentionally carburized and hardened iron) from ordinary wrought iron. Later Jewish tradition sometimes referred to high-quality or hardened iron as a special type of iron (or “Indian iron,” etc.), rather than with a distinct term equivalent to modern “steel.”
The one possible candidate is rare and uncertain. The hapax legomenon peladot (Strong’s 6393) in Nahum 2:3 is sometimes translated “steel” (or metal fittings of the chariots) in modern versions such as the NASB. Lexicographers note possible connections to later Arabic, Syriac, and Persian words for steel. The King James Version has “torches,” and some scholars prefer an emendation. Even if it means steel or hardened iron, it is a single, obscure reference, not ordinary vocabulary.
Limited everyday prevalence. While specialized steel tools and weapons existed, they were not ubiquitous. Bronze remained important, and early ironworking in Israel was restricted (see the Philistine control over smiths in 1 Samuel 13). Biblical writers tended to use the familiar terms barzel (iron) and nechosheth (bronze/copper). They did not systematically distinguish the finer metallurgical grades that modern archaeology identifies as steel.

n short, steel could have been mentioned, since the technology was present. It simply was not lexicalized as a separate category in biblical Hebrew the way it is in modern English, and it was not common enough in ordinary Israelite life to require frequent, unambiguous reference.
