Frankincense is an aromatic gum resin that is still widely used in parts of the Middle East and Africa today. It is produced by scraping the bark of certain native species of trees and then harvesting the beads of resin after they have dried. When burned as incense, it creates a strong and beautiful aroma. In the ancient near east, the cost of frankincense precluded it from being used as a common household air freshener. Rather, the burning of frankincense was closely associated with ceremonial worship of a deity. In this way, the inclusion of frankincense as a gift for Jesus may have indicated that the wise men understood that the prophecy of the newborn king carried with it a claim of deity.
