18 Ezekiel also speaks of him to the same effect, thus: “Thus says the Lord God, Because your heart is lifted up, and you have said, I am God, I sit in the seat of God, in the midst of the sea; yet are you a man, and not God, (though) you have set your heart as the heart of God. Are you wiser than Daniel? Have the wise not instructed you in their wisdom? With your wisdom or with your understanding have you gotten you power, and gold and silver in your treasures? By your great wisdom and by your traffic have you increased your power?
Your heart is lifted up in your power. Therefore thus says the Lord God: Because you have set your heart as the heart of God: behold, therefore I will bring strangers upon you, plagues from the nations: and they shall draw their swords against you, and against the beauty of your wisdom; and they shall level your beauty to destruction; and they shall bring you down; and you shall die by the death of the wounded in the midst of the sea. Will you yet say before them that slay you, I am God? But you are a man, and no God, in the hand of them that wound you. You shall die the deaths of the uncircumcised by the hand of strangers: for I have spoken it, says the Lord.”
