 Note: ☞ Copper is the only metal which occurs native abundantly in large masses; it is found also in various ores, of which the most important are chalcopyrite, chalcocite, cuprite, and malachite. Copper mixed with tin forms bell metal; with a smaller proportion, bronze; and with zinc, it forms brass, pinchbeck, and other alloys.

 Copper
    derived from the Greek kupros (the island of Cyprus), called
    "Cyprian brass," occurs only in the Authorized Version in Ezra
    8:27. Elsewhere the Hebrew word (nehosheth) is improperly
    rendered "brass," and sometimes "steel" (2 Sam. 22:35; Jer.
    15:12). The "bow of steel" (Job 20:24; Ps. 18:34) should have
    been "bow of copper" (or "brass," as in the R.V.). The vessels
    of "fine copper" of Ezra 8:27 were probably similar to those of
    "bright brass" mentioned in 1 Kings 7:45; Dan. 10:6.

      Tubal-cain was the first artificer in brass and iron (Gen.
    4:22). Hiram was noted as a worker in brass (1 Kings 7:14).
    Copper abounded in Palestine (Deut. 8:9; Isa. 60:17; 1 Chr.
    22:3, 14). All sorts of vessels in the tabernacle and the temple
    were made of it (Lev. 6:28; Num. 16:39; 2 Chr. 4:16; Ezra 8:27);
    also weapons of war (1 Sam. 17:5, 6, 38; 2 Sam. 21:16). Iron is
    mentioned only four times (Gen. 4:22; Lev. 26:19; Num. 31:22;
    35:16) in the first four books of Moses, while copper (rendered
    "brass") is mentioned forty times. (See BRASS.)

      We find mention of Alexander (q.v.), a "coppersmith" of
    Ephesus (2 Tim. 4:14).
