This term denotes a dart, javelin, or missile weapon—something designed to be hurled at a target. It appears in Job 41:26 (English 41:18) in the list of weapons useless against Leviathan. The context groups it with spear and armor, indicating a thrown weapon. Darts were lighter than spears, designed for throwing rather than thrusting. The imagery emphasizes the creature's imperviousness to all forms of attack, including projectile weapons.
