Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
FIR' TREE, probably the Aleppo pine (Pinus halepensis), which is almost as large as the cedar, is now found on Lebanon, and was formerly doubtless abundant through Palestine, Hos 14:8. Sometimes the cypress and juniper may have been included under this name, as well as other pines found here. The fir was used for shipbuilding, Eze 27:5, musical instruments, 2 Sam 6:5, and in the frame-, and ornamental, work of costly edifices, 1 Kgs 5:8, scripture]1 Kgs. 5:10[/scripture];1 Kgs 6:15, 1 Kgs 6:34; 1 Kgs 9:11; 2 Chr 2:8; 2 Chr 3:5; Song 1:17.
The fir is still used in the manufacture of harps, lutes, guitars, etc. It was a tall, straight tree, of fine appearance, in the tops of which the storks built their nests, Ps 104:17. Hence it is used to illustrate power or grandeur, 2 Kgs 19:23; Isa 14:8; Isa 37:24; and in Nah 2:3 the brandishing of weapons of war is compared to the shaking of the tops of fir trees by a violent wind. The springing up of the fir is emblematical of verdure and plenty, Isa 41:19;Isa 55:12;Isa 60:13.
