Horn
Horns in the biblical world served as both practical objects and powerful symbols. As physical objects, animal horns were perforated at the tip to make trumpets for signaling in battle and worship (Joshua 6:4–5), and hollow horns served as oil flasks (1 Samuel 16:1). The four corners of the altar of burnt offering and the altar of incense were fashioned as projecting horns (qarnōt), to which worshippers could cling for refuge and to which blood was applied in atoning rituals.
As a symbol, the horn represented power, strength, and royal dignity—the natural force of a horned animal applied metaphorically to human or divine authority. Hannah's prayer (1 Samuel 2:1) exults that God has exalted her horn; the Psalms repeatedly speak of God exalting or humbling horns of nations and individuals (Psalm 75:4–5, 10; 89:17). Daniel's visions use horns as symbols for kings and kingdoms (Daniel 7–8), a usage continued in Revelation (13:1; 17:3). The messianic horn of David (Psalm 132:17; Luke 1:69) became a title for the anointed deliverer who would restore Israel's strength. The range of horn symbolism—from musical instrument to atoning altar to prophetic imagery—reflects its pervasive importance in Israelite religion and thought.
