Ezekiel 28:2

“Because your heart is lifted up, and you have said, ‘I am a god (or ‘I am El'), I sit in the seat of the gods (or ‘of God'), in the midst of the seas'. Yet you are a man and not a god (or ‘not El'), although you set your heart as the heart of the gods.”

There has been much debate about what this king actually claimed for himself. Usually Mediterranean kings, in contrast with Egyptian pharaohs, did not see themselves as fully divine, but rather as chosen servants of the gods. However, there were exceptions, and taking it at face value this was one. Certainly he was guilty of overweening pride. But this king also appears to have seen himself as a god, or at least as a godlike figure (there were various levels of gods), and Tyre as the seat of the gods. And this view would have been expected of his people. This in itself brought Tyre under condemnation. They had usurped the throne of God.

But he is warned that he is in fact only a man. He is not a god (compare Isaiah 31:3), even though he has set his heart on god-like status..

El was the father figure among the gods, but the word also simply meant ‘a god', or sometimes God, especially in poetry. The plural ‘elohim' could mean ‘gods', or when applied to Yahweh ‘God' (the plural showing intensity), or even ‘heavenly beings'.
