A curious verse grabbed my attention yesterday: Ezekiel 28:2. In it God commands the prophet Ezekiel to declare to the prince of Tyre, “‘In the pride of your heart you say, ‘I am a god; I sit on the throne of a god in the heart of the seas.’ But you are a mere mortal and not a god, though you think you are as wise as a god.”
It occured to me that “a god in the heart of the seas” sounds a lot like Poseidon, so I looked further afield, beyond the Bible. It turns out that Agenor, the Phoenician king of Tyre in Greek legend, was said to be a son of Poseidon. It was not uncommon for the writers of the Bible to avoid naming gods other than God directly and instead rely on allusion. I am now fairly confident it is Poseidon that the Bible is alluding to here.
