For all his efforts to lead the Israelites to the Promised Land, Moses does not enter it. Having disobeyed God during the years of wandering in the desert, he is allowed to see the land from Mount Nebo. Before ascending the mountain, Moses gives a final word to the people of Israel. In the Bible, that word is a lengthy blessing recorded in Deuteronomy 33 that names each tribe. He then goes to Mount Nebo and to death, buried by God himself in an unknown grave in Deuteronomy 34.
The Moses of “The Ten Commandments” also climbs Mount Nebo after offering a final word. But he gives this word to a select few only, and it is taken from the Book of Leviticus. “Go,” he says, “proclaim liberty throughout the land unto all the inhabitants thereof” (via YouTube). This is the same verse inscribed on the Liberty Bell in Philadelphia, per the National Parks Service.
This may not have been a coincidence. The Guardian’s review of “The Ten Commandments” detects a Cold War allegory to the film. Cecil B. DeMille, a very conservative man, invited such readings himself in his introduction. “Are men the property of the state,” he asked, “or are they free souls under God? This same battle continues throughout the world today.” Without explicitly calling out Communism or the Soviet Union by name, the implication was that they were the modern-day dictators he was tying back to Rameses.
