When the God of the Universe gives someone a new beginning, it is a radical one. Our prime example is the Children of Israel in our current Torah portion. He dramatically redeems them from Pharaoh and the house of bondage and transforms them from a horde of slaves into a holy nation of purpose. And to seal this transformation He gave the people He redeemed a new calendar to organize their lives by:
Then the LORD said to Moses, “Go in to Pharaoh, for I have hardened his heart and the heart of his servants, that I may show these signs of mine among them, and that you may tell in the hearing of your son and of your grandson how I have dealt harshly with the Egyptians and what signs I have done among them, that you may know that I am the LORD.” (Exodus 10:1–2)
