When Moses shattered the two tablets of the covenant at the foot of Mount Sinai, something extraordinary happened to the sacred letters engraved upon them. According to the Mekhilta, the letters did not simply fall to the ground with the broken stone. They flew upward, returning to Heaven from where they had come.
The rabbis found a proof-text for this remarkable tradition in (Proverbs 23:5): "If you turn your eyes from it, it is gone... and flies to Heaven." The verse speaks of wealth that sprouts wings and vanishes, but the sages read it as a description of Torah itself. The moment Moses averted his gaze from the tablets, the moment he let go and hurled them downward, the holy letters detached from the stone and ascended back to their divine source.
This teaching carries a profound implication. The tablets were not merely stone with writing carved into them. The letters were living things, spiritual entities that had descended from Heaven to dwell in physical form. When their vessel was destroyed, they returned home. The stone was just a container. The real Torah was the letters themselves.
The Mekhilta places this tradition alongside another loss Israel suffered that day: the wealth of Egypt, which they had carried out during the Exodus. Just as material riches can vanish in an instant, so too can spiritual riches. Both the writ of Heaven and the gold of Egypt proved impermanent in the hands of a people who had turned to worship the Golden Calf.
