Long ago the majestic cedars of Lebanon (Cedrus libani) completely covered the upper slopes of the Lebanon Mountains on the western and northern sides. Now only a few pockets of these mighty cedars remain. At that time they were mixed, as they are today, with other trees such as Cilician fir, Grecian juniper, cypress, and Calabrian pine.
We know from 1 Kings that Solomon used cedar wood in his palace and in the Temple. Cedar was used for beams, boards, pillars, and ceilings. Historians tell us that the Assyrians also hauled cedars to their land for use in buildings. Nebuchadnezzar of Babylon also imported cedars from Lebanon. In some versions of Isaiah we read that people made idols of cedar and oak (44:14-20). Finally, when the Temple was rebuilt by the returning exiles (Ezra 3:7), they again cut down cedar trees to grace the house of God.
In 2 Samuel, 1-2 Kings, 1-2 Chronicles and Ezra, when Lebanon is specifically mentioned, there can be no doubt that ’erez is Cedrus libani, the “cedar of Lebanon,” although it is possible that sometimes the word was used loosely to include various evergreen trees.
In the description of the purification rituals (Leviticus 14:4 at al.), the word ’erez probably refers to the Phoenician juniper tree, since that was the only cedar-like tree in the Sinai Desert.
Description Cedar trees can reach 30 meters (100 feet) high with a trunk more than 2 meters (7 feet) in diameter. The leaves of true cedars are not flat like those of most trees, but consist of tufts of dark green, shiny spines. (The cedars in North America have a flatter type of spine than the biblical cedar.) The wood is fragrant and resistant to insects. Cedars bear cones and can live to be two or three thousand years old.
The cedar of Lebanon is famous for its large size (see Isaiah 2:13 et al.), and for the fragrance of its wood. Psalm 92:12 links the cedar to righteousness, that is, presumably, to its straightness and height above other trees. The cedar is the national emblem of Lebanon.
Cedrus species are found in the mountains of North Africa, in the Himalayas, in India, and in North America. Translators in these places, should, of course, use the local name in nonfigurative references. In sub Saharan Africa, translators can transliterate from Hebrew (’erez), Greek (kedar), English (sedar), or another major language, or they can take a generic solution such as “large, beautiful tree.” In poetic passages (wisdom literature and prophecy), some translators may wish to use a cultural equivalent with these traits. In Africa, according to Burkhill (The Useful Plants of West Tropical Africa, volume 4. Kew: Royal Botanic Gardens, 1985), the Pink Mahogany Guarea cedrata is also called the pink African cedar because of the cedar-like scent of its timber. Likewise, some people in India and Australia use “cedar” to refer to the toon because of its reddish wood. I do not recommend such substitutes in historical passages, since the ’erez is not related to these trees. In some figurative passages, however, the substitution could be effective, since all are large trees with reddish wood. However, each passage has to be evaluated to determine the intended effect of the image.
