Thistle
Thistles are among the thorny plants that proliferate in Palestine and appear frequently in biblical metaphor. They are associated in Scripture with the curse upon the ground following the fall: "thorns also and thistles shall it bring forth to thee" (Gen. 3:18). Their appearance on neglected land became a symbol of desolation and divine judgment (Hos. 10:8). In Amaziah's confrontation with Jehoash, the parable of a thistle presuming to negotiate with a cedar captures the folly of disproportionate ambition (2 Kings 14:9).
Several Hebrew and Greek words are translated variously as thistles, thorns, or briers in English, and the distinction is not always maintained consistently. The many thorny plants of Palestine served as natural illustrations of the hardship of cursed ground, the danger of complacency, and the encroachment of spiritual neglect on what had been fruitful.
