Acacia
(Heb. shittim) Ex. 25:5, R.V. probably the Acacia seyal (the gum-arabic tree); called the "shittah" tree (Isa. 41:19). Its wood is called shittim wood (Ex. 26:15, 26; 25:10, 13, 23, 28, etc.). This species (A. seyal) is like the hawthorn, a gnarled and thorny tree. It yields the gum-arabic of commerce. It is found in abundance in the Sinaitic peninsula.

Oil-tree
(Isa. 41:19; R.V. marg., "oleaster"), Heb. etz shemen, rendered "olive tree" in 1 Kings 6:23, 31, 32, 33 (R.V., "olive wood") and "pine branches" in Neh. 8:15 (R.V., "branches of wild olive"), was some tree distinct from the olive. It was probably the oleaster (Eleagnus angustifolius), which grows abundantly in almost all parts of Palestine, especially about Hebron and Samaria. "It has a fine hard wood," says Tristram, "and yields an inferior oil, but it has no relationship to the olive, which, however, it resembles in general appearance."

Fir
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. (See [210]PINE.)
