Nebuchadnezzar, king of Babylon, stood as the supreme example of human arrogance brought low. The Mekhilta recounts how this mighty ruler dared to place himself above all creation. (Isaiah 14:13) records his boast: "You said in your heart: I will climb to the heavens." He wanted to ascend beyond human reach.
Nebuchadnezzar declared that he would make himself a little cloud and live within it — suspended between earth and heaven, answerable to no one. (Isaiah 14:14) captures his ultimate ambition: "I will mount the heights of a cloud." He sought to wrap himself in the imagery of the divine, dwelling among the clouds like God Himself.
But the Holy One Blessed be He responded with devastating precision. "You wished to separate yourself from men," God declared. "In the end, they will separate themselves from you." The punishment mirrored the crime. Nebuchadnezzar wanted to be set apart in glory. He was set apart in degradation instead.
(Daniel 4:25-30) records the fulfillment. Nebuchadnezzar was driven from among men, made to eat grass like cattle, his body drenched with the dew of heaven until his hair grew like eagles' feathers and his nails like birds' claws. The man who wanted to live in a cloud was cast down to live among beasts. The Mekhilta DeRabbi Yishmael (Tractate Shirah 6:8) holds him up as proof that God brings down every empire that exalts itself beyond measure.
