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 Israel (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 T0000641.)

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