In 180 b.c., a Jerusalem scribe recorded the priesthood lineages dating from the Sinai desert of 1400 b.c. to his own era. In this text, Aaron steps toward the smoking bronze altar and lifts slaughter knives above bound oxen. The desert sun beats down on the enclosed courtyard. Arid winds trap the thick scent of burning animal fat, copper blood, and pungent incense around the working men.
Moses appointed Aaron and his sons to manage the sacrificial fires and maintain order among the tribes. The Most High gave the priesthood a perpetual claim to the offerings of the altar. A slaughtered bull yielded roughly 400 pounds of dressed beef. By religious law, the working priests kept the breast and right thigh of each animal. This regular supply of meat kept the Levitical families alive in a barren land. To mark Aaron's authority, craftsmen wove him a ceremonial robe dyed with rare sea-snail extracts. That purple wool cost the equivalent of ten years of a common laborer's wages.
The hem of Aaron's woven robe carried alternating pomegranates and small golden bells. As he walked across the stone floor of the sanctuary, the metal bells rang out to signal his movements inside the holy room. This noise served a strict mechanical purpose. If the ringing stopped, the waiting crowd outside knew the priest had collapsed or died during his work. Authority in this system required wearing a heavy, audible warning device that tracked a man's every step.
Leadership is a heavy garment that strips a man of privacy and forces him to prove his labor with every step.
The Levitical slaughterhouses and golden robes vanished when Roman legions burned the Jerusalem temple to the ground in a.d. 70. All that remained of the sacrificial covenant was a scattered class of priests without an altar, remembered only in scribal archives and the family names of their descendants.
