(Hebrews teashshur), mentioned in Isaiah 60:13; 41:19, was, according to some, a species of cedar growing in Lebanon. The words of Ezek. 27:6 literally translated are, "Thy benches they have made of ivory, the daughter of the ashur tree," i.e., inlaid with ashur wood. The ashur is the box-tree, and accordingly the Revised Version rightly reads "inlaid in box wood." This is the Buxus sempervirens of botanists. It is remarkable for the beauty of its evergreen foliage and for the utility of its hard and durable wood.

box'-tre (te'ashshur; Isaiah 41:19; Isaiah 60:13, "boxwood" Ezekiel 27:6): A tree of uncertain identity, which must once have been common in the forests of Lebanon. According to Post (HDB, I, 313), "The only species of box found in Bible lands is Buxus longifolia, which is a shrub from 2 to 3 ft. high. It does not grow South of Mt. Cassius and it is unlikely that it did in historical times."
As an alternative to the box the cypress, Cupressus sempervirens-known in Arabic as Sherbin-has been suggested. It is a fine tree and was probably once plentiful, but as it seems to answer to the berosh (see FIR), it cannot well be the te'ashshur. There is nothing certain to go upon.
