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