אֹרֶן m. the name of a tree, of the wood of which idols were carved, without doubt a species of pine, Isaiah 44:14. In Talmud. Babyl. (Para, fol. 96, 1), there are joined עצי ארזים ארנים וברושים. LXX. πίτυς. Vulg. pinus.

As to the etymology, אֹרֶן like תֹּרֶן, appears to denote a very lofty tree, which when shaken above by the wind, gives forth a tremulous sound (רנן); see under the word תֹּרֶן ; either אָרַן may be regarded as denoting the same as אָנַן, or else אֹרֶן may be taken from the root רָנַן itself, contr. for אָרְנַן, as תֹּרֶן for תָּרְנַן, מֹרֶךְ from רָכַךְ. Others understand an ash or an elder, from the similarity of sound; ornus, alnus.

(2) [Oren], pr.n. m., 1 Chronicles 2:25.
