parzel

Standard lexica gloss the word without hesitation as "iron" (HALOT, Aramaic section, s.v. פַּרְזֶל; Vogt, Lexicon of Biblical Aramaic). It is the common Semitic term for the metal, cognate with Hebrew בַּרְזֶל, Akkadian parzillu, and Ugaritic brḏl, with the initial labial alternating between b and p across the dialects. Most scholars regard it as a culture-word that spread with iron metallurgy rather than an inherited Semitic root, and a non-Semitic (often Anatolian) source has been proposed, though the exact origin remains unsettled; this etymological question does not touch the agreed sense. In Daniel the term is confined to the statue of Nebuchadnezzar's first dream, the fourth beast of Daniel's night vision, the iron band around the stump in the second dream, and the list of idol-materials at Belshazzar's feast. The commentaries (Montgomery, ICC; Collins, Hermeneia; Goldingay, WBC) read iron in the statue and the beast as the imagery of the strongest and most destructive of metals, the emblem of an empire that breaks all others, while the iron-and-clay feet figure a realm both formidable and internally unstable. The identification of that empire is a matter of the visions' interpretation, not of the word itself.
