The precious aromatic gum resin harvested from frankincense trees, prized throughout the ancient world for religious rituals. Matthew records it among the Magi's gifts to the infant Jesus—gold for a king, frankincense for deity. Revelation includes it in the cargo list of fallen Babylon, showing its economic value. Harvested primarily in Arabia and Somalia, frankincense was burned to create fragrant smoke ascending to heaven, making it the perfect symbol for prayer and worship.
