Paradox #1
The contradiction or inconsistency in Exodus 19:18 could be related to its description of Mount Sinai, which some historians and archaeologists find lacking evidence for such a dramatic event, like smoke and fire, in the archaeological record.

This raises questions about the historical accuracy of this depiction.
