Easton's Bible Dictionary (1.) Hebrews haral, "pricking" or "burning," Proverbs 24:30, 31 (R.V. marg., "wild vetches"); Job 30:7; Zephaniah 2:9. Many have supposed that some thorny or prickly plant is intended by this word, such as the bramble, the thistle, the wild plum, the cactus or prickly pear, etc. It may probably be a species of mustard, the Sinapis arvensis, which is a pernicious weed abounding in corn-fields. Tristram thinks that this word "designates the prickly acanthus (Acanthus spinosus), a very common and troublesome weed in the plains of Palestine." (2.) Hebrews qimmosh, Isaiah 34:13; Hosea 9:6; Proverbs 24:31 (in both versions, "thorns"). This word has been regarded as denoting thorns, thistles, wild camomile; but probably it is correctly rendered "nettle," the Urtica pilulifera, "a tall and vigorous plant, often 6 feet high, the sting of which is much more severe and irritating than that of our common nettle." Noah Webster's Dictionary 1. (v. t.) To fret or sting; also a plant of the genus Urtica, covered with minute sharp hairs; to irritate or vex; to cause to experience sensations of displeasure or uneasiness not amounting to violent anger. 2. (n.) A plant of the genus Urtica, covered with minute sharp hairs containing a poison that produces a stinging sensation. Urtica gracitis is common in the Northern, and U. chamaedryoides in the Southern, United States. the common European species, U. urens and U. dioica, are also found in the Eastern united States. U. pilulifera is the Roman nettle of England.
