Heb. 'arar, (Jer. 17:6; 48:6), a species of juniper called by
the Arabs by the same name ('arar), the Juniperus sabina or
savin. "Its gloomy, stunted appearance, with its scale-like
leaves pressed close to its gnarled stem, and cropped close by
the wild goats, as it clings to the rocks about Petra, gives
great force to the contrast suggested by the prophet, between
him that trusteth in man, naked and destitute, and the man that
trusteth in the Lord, flourishing as a tree planted by the
waters" (Tristram, Natural History of the Bible).
