(Hebrew: o'ren, Meaning: “tremulous”)
The ash tree is mentioned only Isaiah 44:14 (Revised Version, “fir tree”). It is rendered “pine tree” both in the LXX and Vulgate versions. There is a tree called by the Arabs aran, found still in the valleys of Arabia Petraea, whose leaf resembles that of the mountain ash. This may be the tree meant.
