Steel
The “bow of steel” in (King James Version) 2 Samuel 22:35; Job 20:24; Psalm 18:34 is in the Revised King James Version “bow of brass” (Hebrew: kesheth-nehushah).
In Jeremiah 15:12 the same word is used, and is also rendered in the Revised King James Version “brass.” But more correctly it is copper, as brass in the ordinary sense of the word (an alloy of copper and zinc) was not known to the ancients.
