DID YOU KNOW?
The answer
The king of Babylon. Isaiah 14:4 introduces the song as a taunt "against the king of Babylon". The lines that follow mock a man. The dead kings in Sheol greet him as one of them (Isaiah 14:9-10). He is left unburied, "like a corpse trampled underfoot" (Isaiah 14:19). The chapter never names Satan.
Why it’s interesting
Morning Star and son of Dawn may be mocking titles for the king, drawn from the names of Canaanite gods. The passage was later read as the fall of Satan, and Milton's Paradise Lost tells it that way.
