Tiamat

The Bible includes a number of texts in which God battles and tames the chaotic sea, like Marduk battling Tiamat, who embodies the sea.
But in Gen 1, God is already superior to “the Deep,” which in Hebrew is tehom, a word related to Tiamat.
Satan is labeled "the Assyrian that is in My land" in Isaiah 14, where he is also addressed as the king of Babylon.
Isaiah 14:3-4,12,24-27
It shall come to pass in the day the LORD gives you rest from your sorrow, and from your fear and the hard bondage in which you were made to serve, that you will take up this proverb against the king of Babylon, and say:
“How the oppressor has ceased,
The golden city ceased! ...
How you are fallen from heaven,
O Lucifer, son of the morning!
How you are cut down to the ground,
You who weakened the nations! ...
The LORD of hosts has sworn, saying,
“Surely, as I have thought, so it shall come to pass,
And as I have purposed, so it shall stand:
That I will break the Assyrian in My land,
And on My mountains tread him underfoot.
Then his yoke shall be removed from them,
And his burden removed from their shoulders.
This is the purpose that is purposed against the whole earth,
And this is the hand that is stretched out over all the nations.
For the LORD of hosts has purposed,
And who will annul it?
His hand is stretched out,
And who will turn it back?”

You will notice that the Lord here refers to this king of Babylon as "the Assyrian," and this entire passage is speaking of Lucifer, the one who fell from heaven, who has sought to establish his dominion over the whole earth.

The Lord also addresses Satan under the name "the king of Tyre" in
Ezekiel 28:12-15
“Son of man, take up a lamentation for the king of Tyre, and say to him, ‘Thus says the Lord GOD:
“You were the seal of perfection,
Full of wisdom and perfect in beauty.
You were in Eden, the garden of God;
Every precious stone was your covering:
You were the anointed cherub who covers;
I established you;
You were on the holy mountain of God;
You walked back and forth in the midst of fiery stones.
You were perfect in your ways from the day you were created,
Till iniquity was found in you.

Thus, it makes perfect sense that the Lord is employing these things to teach us concerning Satan, who was indeed in the Garden of Eden; who is described as being a most beautiful creature. His kingdom is represented by the king of Tyre, the king of Babylon, the king of Egypt, and all the world empires throughout the ages. His is the kingdom that will ultimately be brought down at the second coming; "the sinful kingdom," as it is called.
