Ezekiel 10:20

So He drove the man out; and at the east of the garden of Eden He stationed the cherubim and the flaming sword which turned every direction to guard the way to the tree of life.

Now it happened in the thirtieth year, on the fifth day of the fourth month, while I was by the river Chebar among the exiles, that the heavens were opened, and I saw visions of God.

And within it there were figures with the likeness of four living creatures. And this was their appearance: they had the likeness of a man.

And it was like the appearance of the vision which I saw, like the vision which I saw when He came to bring the city to ruin. And the visions were like the vision which I saw by the river Chebar; and I fell on my face.
