The language of the Bible is rich with metaphor. The biblical writers used familiar, everyday objects to symbolize spiritual truth. Symbols are quite common in the poetic and prophetic portions of the Bible. By its very nature, poetry relies heavily on figurative language; when Solomon calls his bride “a lily among thorns” (Song of Solomon 2:2), he is using symbols to declare the desirability and uniqueness of the Shulamite. Prophecy, too, contains much figurative imagery. Isaiah often used trees and forests as symbols of strength (e.g., Isaiah 10:18-19; 32:19). Daniel saw “a goat with a prominent horn between his eyes” who “came from the west . . . without touching the ground” (Daniel 8:5), and we interpret this as a kingdom (Greece) and its king (Alexander the Great) who speedily conquered the world.
