The Ten Plagues has been interpreted as a critique of the idolatry of the Egyptians. What the Egyptians worshipped was mocked through the Ten Plagues. The Egyptians worshipped the Nile River as a god. The frog was a deity. The cow goddess Hathor was adored. The sun god Re was praised. Finally, the slaying of the first born mocked the Pharaoh himself, as the Pharaoh was the son of the sun god. The Egyptians worshipped nature as godly. However, the G-d of Israel is portrayed as beyond. He is other and transcendent. What is natural is not holy in the Torah, but subject to the rule of G-d. Israel's objection to slavery is that it may be natural, but it is not holy. To enslave a person is to degrade that individual. For the Torah, G-d is the source of human dignity and equality. Our value as humans comes from the Beyond. Our dignity is from G-d. The Torah is a revolt against slavery. The narrative teaches our worth as humans. The source of our dignity is the story of the Exodus. Judaism teaches us that G-d is the author of our liberation.
The ten plagues are a protest against the sin of idolatry. What do we idolize in the twenty-first century? Idolatry is still very much with us. Although we do not worship statues, we are still the descendents of the ancient Egyptians. We worship power, wealth, status, beauty and success. We bow down to the material gods of twenty-first century America. This worship is the source of the plagues of our own time. In our worship of our new gods, we are indifferent to others. We neglect issues of genuine concern. We become overwhelmed with intense competition with our neighbors.
The power and might of Egypt have crumbled in the dust. However,
the idea of G-d above any human whim or desire still is the greatest
belief of all time.
