Is found in the English Bible, 1 Kings 19:4,5; Job 30:4; Psalms 120:4. The Hebrew word, however, signifies the plant Genista, or Spanish broom, which is common in the desert regions of Arabia, and has yellowish blossoms and a bitter root.

Juniper
(Heb. rothem), called by the Arabs retem, and known as Spanish broom; ranked under the genus genista. It is a desert shrub, and abounds in many parts of Palestine. In the account of his journey from Akabah to Jerusalem, Dr. Robinson says: "This is the largest and most conspicuous shrub of these deserts, growing thickly in the water-courses and valleys. Our Arabs always selected the place of encampment, if possible, in a spot where it grew, in order to be sheltered by it at night from the wind; and during the day, when they often went on in advance of the camels, we found them not unfrequently sitting or sleeping under a bush of retem to shelter them from the sun. It was in this very desert, a day's journey from Beersheba, that the prophet Elijah lay down and slept beneath the same shrub" (1 Kings 19:4,5). It afforded material for fuel, and also in cases of extremity for human food (Psalms 120:4; Job 30:4). One of the encampments in the wilderness of Paran is called Rithmah, i.e., "place of broom" (Numbers 33:18).
"The Bedawin of Sinai still burn this very plant into a charcoal which throws out the most intense heat."

Juniper
JU'NIPER, n. L. juniperus. A tree or shrub bearing berries of a bluish color, of a warm, pungent, sweet taste, yielding when fresh, by expression, a rich, sweet, aromatic juice. They are useful carminatives and stomachics. The wood of the tree is of a reddish color, hard and durable, and is used in cabinet work and veneering. The oil of juniper mixed with that of nuts makes an excellent varnish; and the resin powdered is used under the name of pounce.
