n.

14c.; Old English had furhwudu “pine wood,” but the modern word is more likely from Old Norse fyri- “fir” or Old Danish fyr, all from Proto-Germanic *furkhon (cf. Old High German foraha, German Föhre “fir”), from PIE root *perkos, originally “oak” (cf. Sanskrit paraktah “the holy fig tree,” Hindi pargai “the evergreen oak,” Latin quercus “oak,” Lombardic fereha “a kind of oak”).

far infrared

the uniform rendering in the Authorized Version (marg. R.V., “cypress”) of _berosh_ (2 Sam. 6:5; 1 Kings 5:8, 10; 6:15, 34; 9:11, etc.), a lofty tree (Isa. 55:13) growing on Lebanon (37:24). Its wood was used in making musical instruments and doors of houses, and for ceilings (2 Chr. 3:5), the decks of ships (Ezek. 27:5), floorings and spear-shafts (Nah. 2:3, R.V.). The true fir (abies) is not found in Palestine, but the pine tree, of which there are four species, is common. The precise kind of tree meant by the “green fir tree” (Hos. 14:8) is uncertain. Some regard it as the sherbin tree, a cypress resembling the cedar; others, the Aleppo or maritime pine (Pinus halepensis), which resembles the Scotch fir; while others think that the “stone-pine” (Pinus pinea) is probably meant.
