Hebrew: tirzah, “hardness”, mentioned only in Isa. 44:14 (Revised Version, “holm tree”.
The oldest Latin version translates this word by ilex, i.e., the evergreen oak, which may possibly have been the tree intended; but there is great probability that our Authorized Version is correct in rendering it “cypress.” This tree grows abundantly on the mountains of Hermon. Its wood is hard and fragrant, and very durable. Its foliage is dark and gloomy. It is an evergreen (Cupressus sempervirens).
