It is the late fifteenth century b.c. Men stand in the hot wind of the Moabite plains. They look across the Jordan River at steep hillsides. Their calves ache from forty years of walking through abrasive sand and jagged ravines. They remember the thick mud of Egypt and the endless labor of lifting seventy pounds of river water by foot to flood vegetable beds. A deep nervous tension hangs in the camp about trusting the open sky for crop survival. The promise of steady autumn rain offers immense relief to exhausted muscles.
Moses addresses the crowd of weary travelers. He issues a final legal contract on the eastern edge of the Jordan. They must choose between strict obedience and immediate ruin. This choice dictates who eats and who starves. The Creator of Heaven and Earth controls the weather. If the people follow his laws, he opens the clouds for the seed time and the harvest. If they rebel, he shuts the sky. The ancient mechanical systems of human effort give way to total reliance on seasonal storms. This land requires constant attention to the law to secure daily bread.
The wooden doorpost serves as the primary boundary line. A man writes the law on the heavy timber of his own house to instruct the next generation. Human memory fails rapidly under the strain of normal labor. Stamping the instructions on a physical doorway forces the mind to acknowledge the contract every time a person walks outside. It transforms an abstract legal concept into a solid object.
A man building a house must nail the rules to his doorframe before he forgets how the roof stays up.
The edict left behind two stone peaks named Gerizim and Ebal. They stand today as permanent geological markers of a severe agricultural contract.
